Subsequent Events [Abstract]
Subsequent Events	In December 19, 2019, the Company announced a stock-for-stock merger with The Rubicon Project, which will create a combined company offering a single partner for transacting CTV, desktop display, video, audio, and mobile inventory across all geographies and auction types. A definitive proxy statement was issued on February 13, 2020 and sent to both companies shareholders for a vote. Based on the number of shares of the Company's common stock outstanding and reserved for issuance as of February 11, 2020 and the number of shares of Rubicon Project common stock outstanding and reserved for issuance as of February 11, 2020, it is estimated that, immediately following completion of the merger, former holders of Telaria common stock will own approximately 47.6% and pre-merger holders of Rubicon Project common stock will own approximately 52.4% of common stock of the combined company on a fully diluted basis. The Merger is expected to be completed to close in early April 2020. The credit facility with Silicon Valley Bank, matures on March 26, 2020. In light of the pending merger with Rubicon Project which is expected to be closed in early April 2020, the Company does not intend to renew the credit facility.
