Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation and Unaudited Interim Financial Information	Basis of Presentation The Company’s unaudited condensed consolidated financial statements are prepared in accordance with accounting principles generally accepted in the U.S. (“GAAP”). The condensed consolidated financial statements include the accounts of all subsidiaries and affiliates in which the Company holds a controlling financial interest as of the date of the condensed consolidated financial statements. The condensed consolidated financial statements include the accounts of The Meet Group and its wholly-owned subsidiaries. All intercompany accounts and transactions have been eliminated in consolidation. Unaudited Interim Financial Information The unaudited condensed consolidated financial statements have been prepared by the Company and reflect all normal, recurring adjustments that, in the opinion of management, are necessary for a fair presentation of the interim financial information. The results of operations for the interim periods presented are not necessarily indicative of the results to be expected for any subsequent quarter or for the year ending December 31, 2018. Certain information and footnote disclosures normally included in financial statements prepared in accordance with GAAP have been condensed or omitted under the rules and regulations of the Securities and Exchange Commission (“SEC”). These unaudited condensed consolidated financial statements and notes included herein should be read in conjunction with the audited consolidated financial statements and notes included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2017, filed with the SEC on March 16, 2018.
Use of Estimates	Use of Estimates The preparation of the Company’s condensed consolidated financial statements in conformity with GAAP requires the Company to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the condensed consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. Significant estimates and assumptions are required in the determination of business combinations, revenue recognition, accounts receivable valuation, the fair value of financial instruments, the valuation of long-lived assets, valuation of deferred tax assets, income taxes, contingencies, goodwill and intangible assets and stock-based compensation. Some of these judgments can be subjective and complex and, consequently, actual results may differ from these estimates. The Company’s estimates often are based on complex judgments, probabilities and assumptions that it believes to be reasonable but that are inherently uncertain and unpredictable. For any given individual estimate or assumption made by the Company, there may also be other estimates or assumptions that are reasonable. The Company regularly evaluates its estimates and assumptions using historical experience and other factors, including the economic environment. As future events and their effects cannot be determined with precision, the Company’s estimates and assumptions may prove to be incomplete or inaccurate, or unanticipated events and circumstances may occur that might cause it to change those estimates and assumptions. Market conditions, such as illiquid credit markets, volatile equity markets, dramatic fluctuations in foreign currency rates and economic downturns, can increase the uncertainty already inherent in its estimates and assumptions. The Company adjusts its estimates and assumptions when facts and circumstances indicate the need for change. Those changes generally will be reflected in the Company’s condensed consolidated financial statements on a prospective basis unless they are required to be treated retrospectively under the relevant accounting standard. It is possible that other professionals, applying reasonable judgment to the same facts and circumstances, could develop and support a range of alternative estimated amounts. The Company is also subject to other risks and uncertainties that may cause actual results to differ from estimated amounts, such as changes in competition, litigation, legislation and regulations.
Revenue Recognition and Recent Issued Accounting Standards	Recent Issued Accounting Standards In February 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842). The new standard establishes a right-of-use (ROU) model that requires a lessee to record an ROU asset and a lease liability on the balance sheet for all leases with terms longer than 12 months. Leases will be classified as either finance or operating, with classification affecting the pattern of expense recognition in the income statement. ASU No. 2016-2 is effective for annual periods beginning after December 15, 2018, and annual and interim periods thereafter, with early adoption permitted. A modified retrospective transition approach is required for lessees for capital and operating leases existing at, or entered into after, the beginning of the earliest comparative period presented in the financial statements, with certain practical expedients available. The Company is currently evaluating the impact that the adoption of this new standard will have on its consolidated financial statements. In August 2016, the FASB issued ASU No. 2016-15, Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments, providing additional guidance on several cash flow classification issues, with the goal of the update to reduce the current and potential future diversity in practice. The amendments in this update are effective for fiscal years beginning after December 15, 2017, and interim periods within those fiscal years. The adoption of ASU No. 2016-15 did not have any impact on the Company’s consolidated financial statements. In February 2018, the FASB issued ASU 2018-02, Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income. The amendment allows an entity to elect to reclassify the stranded tax effects resulting from the change in income tax rate from the Tax Cuts and Jobs Act from accumulated other comprehensive income to retained earnings. The amendments in this update are effective for periods beginning after December 15, 2018. Early adoption is permitted. The Company is currently evaluating the impact that the adoption of this new standard will have on its consolidated financial statements. Revenue Recognition On January 1, 2018, the Company adopted ASC Topic 606 “Revenue from Contracts with Customers,” (“ASC 606”) using the cumulative effect method (modified retrospective method) and applied to those contracts with customers which were not completed as of January 1, 2018. Results for reporting periods beginning after January 1, 2018 are presented under ASC 606, while prior period amounts are unadjusted and continue to be reported in accordance with the Company’s historic accounting under ASC Topic 605, “Revenue Recognition” (“ASC 605”). The Company recorded a net reduction to opening deferred revenue and a corresponding increase to retained earnings of $0.02 million as of January 1, 2018 due to the cumulative impact of adopting ASC 606. The impact was related to MeetMe+ subscriptions, which were previously recognized using the revenue policy for credits under ASC 605. Under ASC 606, MeetMe+ subscription revenue will be recognized over the subscription period using a mid-month convention beginning on January 1, 2018. See Note 12— Revenue for further detail on revenue recognition.
Fair Value Measurements	Fair Value Measurements The fair values of the Company’s financial instruments reflect the amounts that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date (exit price). The carrying amounts of the Company’s financial instruments of cash, cash equivalents, restricted cash, accounts receivable, accounts payable, accrued liabilities and deferred revenue approximate fair value due to their short maturities. Certain derivatives are carried at fair value as disclosed in Note 3— Fair Value Measurements. The Company has evaluated the estimated fair value of financial instruments using available market information and management’s estimates. The use of different market assumptions and/or estimation methodologies could have a significant effect on the estimated fair value amounts. In addition, the Company carries its contingent consideration liabilities related to acquisitions at fair value. In accordance with the three-tier fair value hierarchy, the Company determined the fair value of its contingent consideration liabilities using the income approach with assumed discount rates and payment probabilities. The income approach uses Level 3, or unobservable, inputs as defined under the accounting guidance for fair value measurements. At December 31, 2017, the Company’s contingent consideration liability had a fair value of $5.0 million. The Company paid the full amount of the contingent consideration in April 2018. See Note 2— Acquisitions for more information regarding the Company’s contingent consideration liability. As part of the Lovoo Acquisition the Company amended and restated its term loan and revolving credit facility. The Company carries a term loan facility with an outstanding balance at June 30, 2018 and December 31, 2017 of $48.8 million and $56.3 million, respectively. The outstanding balance as of June 30, 2018 and December 31, 2017 approximates fair value due to the variable market interest rates and relatively short maturity associated with the Term Loan Facility. See Note 6— Long-Term Debt for more information regarding the Company’s credit facilities. The Company leases certain fixed assets under capital leases that expire through 2021. The capital leases are for the Company's data centers, printers and other furniture in the Company's German offices. The outstanding balance as of June 30, 2018 and December 31, 2017 approximates fair value due to the relatively short maturities associated with these capital leases.
Foreign Currency	Foreign Currency The functional currency of our foreign subsidiaries is the local currency. The financial statements of these subsidiaries are translated to U.S. dollars using period-end rates of exchange for assets and liabilities and average quarterly rates of exchange for revenues and expenses. Translation gains (losses) are recorded in accumulated other comprehensive income (loss) as a component of stockholders’ equity. Net gains and losses resulting from foreign exchange transactions are included in other income (expense).
Net Income (Loss) per Share	Net Income (Loss) per Share Basic net income (loss) per share is computed by dividing net income (loss) attributable to common stockholders by the weighted average number of common shares outstanding. Diluted net income (loss) per share is computed by dividing net income (loss) attributable to common stockholders by the weighted average number of common shares and common stock equivalents outstanding, calculated under the treasury stock method for options, unvested restricted stock awards, unvested in-the-money performance share units and warrants using the average market prices during the period.
Significant Customers and Concentration of Credit Risk	Significant Customers and Concentration of Credit Risk Financial instruments that potentially subject the Company to significant concentrations of credit risk consist primarily of cash, cash equivalents, restricted cash and accounts receivable. The Company invests its excess cash in high-quality, liquid money market funds maintained by major U.S. banks and financial institutions. The Company has not experienced any losses on its cash equivalents, including restricted cash or money market funds. The Company performs ongoing credit evaluations of its customers and generally does not require collateral. The Company has no recent history of significant losses from uncollectible accounts. During the six months ended June 30, 2018 and 2017, two and three customers, all of which were advertising aggregators (which represent thousands of advertisers) and customer payment processors, comprised approximately 49% and 46% of total revenues, respectively. Three and five customers, which were advertising aggregators and customer payment processors, comprised approximately 51% and 61% of accounts receivable as of June 30, 2018 and December 31, 2017, respectively. The Company does not expect its current or future credit risk exposure to have a significant impact on its operations, however, there can be no assurance that the Company’s business will not experience any adverse impact from credit risk in the future.
Reclassifications	Reclassifications In the statement of comprehensive income (loss) for the six months ended June 30, 2018, approximately $1.7 million related to the three months ended March 31, 2018 was reclassified from unrealized gain (loss) on derivative instruments to foreign currency translation adjustment. This reclassification had no impact on net other comprehensive income (loss) for the three and six month periods ended ended June 30, 2018 or accumulated comprehensive loss as of June 30, 2018.
Revenue	The Company recognizes revenue when control of the promised good or service is transferred to the customer in an amount that the Company expects to be entitled in exchange for the good or service. Advertising Revenue Advertising revenue is comprised of mobile and web advertising. Within each revenue stream, the Company has one performance obligation to publish advertisements as specified by the respective contracts. The amount of consideration that the Company expects to receive for the services is variable based on the volume of advertisement impressions. The Company does not offer any discounts or free impressions and has not historically experienced any collectability issues. The Company also recognizes revenue from cross-platform/social theater and cost-per-action (“CPA”) offers. Each of these revenue streams has one performance obligation. For cross-platform/social theater contracts, the consideration promised is fixed per ad campaign and term, and required services to be delivered. However, the monthly revenue could vary depending on the actual delivery of impressions throughout the contract term. These contracts are typically based on cost per thousand (“CPM”) rates and number of impressions served due to traffic volume and the specific ad campaign. For CPA offers, the consideration promised is variable based on a revenue share rate, and/or based on the number of actions delivered per the agreement. As such, the Company recognizes all actual advertising revenues from impressions or actions delivered on a monthly basis rather than estimating revenue at the beginning of the period. The Company has transactions with several partners that qualify for principal agent considerations. The Company recognizes revenue, net of amounts retained by the third-party partners, pursuant to revenue sharing agreements with advertising networks. The form of the agreements was such that the Company provided services in exchange for a fee. The Company determines only the fee for providing its services to advertising agencies and has no latitude in establishing prices with third party advertisers. In instances where the Company works directly with an advertiser, revenue is recognized on a gross basis. The Company is the primary obligor in arrangements made with direct advertisers, as there is no third-party facilitating or managing the sales process. The Company is solely responsible for determining price, product or service specifications, and which advertisers to use. The Company assumes all credit risk in the sales arrangements made with direct advertisers. The Company has determined that the performance obligation under the advertising revenue streams is recognized ratably over time utilizing the “Right to Invoice” practical expedient as customers simultaneously consume and receive benefits of the advertisement impressions. Deferred Revenue The Company records deferred revenue when the consideration for a good or service is received in advance of its performing the obligation. The deferred revenue balance for the six months ended June 30, 2018 increased $46.2 million due to subscription and in-app purchases consideration received in advance of providing the good or service to the customers. This amount was offset by $45.5 million revenue recognized from the deferred revenue balance as of December 31, 2017 due to performance obligations satisfied during the six months ended June 30, 2018. ASC 606 Practical Expedient Elections The Company elected the following practical expedients in applying ASC 606 to its revenue streams: Portfolio Approach - Contracts within each revenue stream have similar characteristics and the Company expects that the effects on the financial statements would not differ materially from applying this guidance to the individual contracts. As such, the Company applied the portfolio approach to its contracts. Sales Tax Exclusion from Transaction Price - The Company does not collect sales tax for advertising revenue. Sales taxes are added to the transaction price by the payment processors for subscription and in-app purchases, when applicable. However, these sales taxes are not included in the Company’s consideration amount. Contract Costs - The Company does not incur costs to obtain or fulfill contracts in most revenue streams. There are sales commissions incurred for Social Theater contracts, however these contracts are typically for a period of less than a year. As the costs are expected to be recognized is one year or less, these costs are recorded within sales and marketing expenses rather than being deferred and recognized over the term of the contract. Right to Invoice - Revenue from advertising contracts is recognized over time based on the Company’s performance completed to date. The Company will apply the invoice expedient and recognize revenue in the amount to which the entity has a right to invoice as measured by the amount of impressions or actions delivered within each period. Unsatisfied Performance Obligations - The Company’s disclosures exclude the value of unsatisfied performance obligations for (i) its contracts with an original expected length of one year or less and (ii) contracts for which the Company recognizes revenue at the amount to which it has the right to invoice for performance to date. User Pay Revenue User pay revenue is earned from in-app purchase products and subscriptions sold to mobile application and website users. The Company offers in-app products such as Credits, Points, Gold, Diamonds and Icebreakers. Users purchase these products to exchange for the Company’s virtual products. These products allow users to engage with other users on the applications and in live video, and put users in the spotlight, helping them get more attention from the community in order to meet more people faster. Platform users do not own the Credits, Points, Gold, Diamonds or Icebreakers but have a limited right to use the Credits, Points, Gold, Diamonds or Icebreakers on virtual products offered for sale on the Company’s platforms. Credits may be gifted to other user accounts in the form of Diamonds, and Diamonds may be redeemed for cash. Except for Diamonds, the Company’s in-app products are not transferable, cannot be sold or exchanged outside of the Company’s platforms, are not redeemable for any sum of money, and can only be used on the Company’s platforms. In-app products are recorded in deferred revenue when purchased and recognized as revenue over time when: (i) the Credits, Points, Gold, Diamonds or Icebreakers are used by the customer; or (ii) the Company determines the likelihood of the Credits, Points, Gold, Diamonds or Icebreakers being redeemed by the customer is remote (breakage) and there is not a legal obligation to remit the unredeemed Credits, Points, Gold, Diamonds or Icebreakers to the relevant jurisdiction. The determination of the breakage rate is based upon Company-specific historical redemption patterns. Breakage is recognized in revenue as the Credits, Points, Gold and Icebreakers are used on a pro rata basis over a three or six-month period (life of the user) beginning at the date of the sale and are included in revenue in the condensed consolidated statements of operations and comprehensive income. Breakage recognized during the six months ended June 30, 2018 and 2017 was $1.6 million and $0.7 million, respectively. For MeetMe+, Tagged, Skout and Lovoo subscription based products, the Company recognizes revenue over the term of the subscription. Under ASC 606, user pay revenue has a single performance obligation. Subscriptions provide customers with premium access to the application and include credits on MeetMe+ while in app purchases are satisfied by standing ready to allow users to exchange credits for virtual products. The consideration received for these services is fixed at the time of purchase. The customer simultaneously receives and consumes the benefits of user pay features as the Company performs the services. Revenue is recorded in deferred revenue when purchased by customer and recognized as revenue over time as the performance obligation is satisfied. The adoption of ASC 606 primarily affected the timing of revenue recognition for MeetMe+ subscriptions, which were historically recognized using the revenue recognition methodology for credits. MeetMe+ subscription revenue will be recognized over the subscription period using a mid-month convention beginning on January 1, 2018.
