Business Combination and Asset Acquisition [Abstract]
Business Combination Disclosure	Business CombinationsOn March 21, 2019, the Company entered into a merger agreement (the "Merger Agreement") with Zoosk, Inc. ("Zoosk"), to acquire 100% of the common stock of Zoosk with a combination of cash and Spark Networks ADS for consideration of $262.2 million. Zoosk became a wholly owned subsidiary of the Company. The Merger Agreement provided for cash consideration of $105.0 million, which included $10.0 million of the cash consideration held back by the Company in order to satisfy any indemnity obligations of the holders of shares of Zoosk Capital Stock, Vested Options and Cash Out Warrants. The holdback amount accrues interest at 2.0% annually from July 1, 2019 until December 31, 2020, and 12.0% annually thereafter. The holdback amount, including accrued interest balances as of December 31, 2021 and 2020 of $1.5 million and $0.3 million, respectively, is included as Other liabilities within the Consolidated Balance Sheets. Further, $1.0 million of other consideration was placed in escrow for purposes of satisfying post-closing purchase price adjustments, if any. The Company determined that the final merger aggregate adjusted cash consideration resulted in a final adjustment surplus of $0.5 million, which was paid in February 2020. The Company financed the cash consideration through borrowings under the Senior Secured Facilities Agreement as described in Note 9—Long-term Debt.
