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, 2019. 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, 2018, filed with the SEC on March 8, 2019.
Use of Estimates	Use of Estimates The preparation of the Company’s 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 revenue recognition, accounting for business combinations, 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, video broadcaster fees 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 downturn, 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.
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, accounts receivable, accounts payable, accrued liabilities and deferred revenue approximate fair value due to their short maturities. 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 June 30, 2019, the Company’s contingent consideration liability had a fair value of $1.8 million. See Note 2— Acquisitions for more information regarding the Company’s contingent consideration liability. The Company carries a term loan facility with an outstanding balance at June 30, 2019 and December 31, 2018 of $25.9 million and $36.9 million, respectively. As part of the Growlr Acquisition (as defined in Note 2— Acquisitions), the Company drew down $7.0 million on its revolving credit facility. The outstanding balance on the Company’s revolving credit facility at June 30, 2019 was $7.0 million. The outstanding balances of the Company’s term loan and revolving credit facilities as of June 30, 2019 and December 31, 2018 approximate fair value due to the variable market interest rates and relatively short maturity associated with them. See Note 6— Long-Term Debt for more information regarding the Company’s credit facilities. The Company leases its operating facilities in the U.S. and Germany under certain noncancelable operating leases that expire through 2023. The Company also 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 of operating and finance leases as of June 30, 2019 and December 31, 2018 approximates fair value due to their relatively short maturities. The Company records all derivatives on the balance sheet at fair value. The accounting for changes in the fair value of derivatives depends on the intended use of the derivative, whether the Company has elected to designate a derivative in a hedging relationship and apply hedge accounting and whether the hedging relationship has satisfied the criteria necessary to apply hedge accounting. Derivatives designated and qualifying as a hedge of the exposure to changes in the fair value of an asset, liability, or firm commitment attributable to a particular risk, such as interest rate risk, are considered fair value hedges. Derivatives designated and qualifying as a hedge of the exposure to variability in expected future cash flows, or other types of forecasted transactions, are considered cash flow hedges. Derivatives may also be designated as hedges of the foreign currency exposure of a net investment in a foreign operation. Hedge accounting generally provides for the matching of the timing of gain or loss recognition on the hedging instrument with the recognition of the changes in the fair value of the hedged asset or liability that are attributable to the hedged risk in a fair value hedge or the earnings effect of the hedged forecasted transactions in a cash flow hedge. The Company may enter into derivative contracts that are intended to economically hedge certain of its risk, even though hedge accounting does not apply or the Company elects not to apply hedge accounting. The Company is measuring the credit risk of its derivative financial instruments that are subject to master netting agreements on a net basis by counterparty portfolio.
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 (“RSAs”), unvested in-the-money performance share units (“PSUs”) 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, 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 and cash equivalents, including 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, 2019 and 2018, two customers, both of which were advertising aggregators (which represent thousands of advertisers) and customer payment processors, comprised approximately 61% and 49% of total revenues, respectively. Two and three customers, which were advertising aggregators and customer payment processors, comprised approximately 44% and 36% of accounts receivable as of June 30, 2019 and December 31, 2018, 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.
Recent Issued Accounting Standards	Recent Issued Accounting Standards In February 2016, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2016-02, Leases (Topic 842). The new standard establishes a right-of-use (“ROU”) model that requires a lessee to record a 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. 2016-02 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 an option 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. In July 2018, the FASB issued ASU No. 2018-11, Leases (Topic 842), which adds an optional transition method allowing entities to apply the new lease accounting rules through a cumulative-effect adjustment to the opening balance of retained earnings in the initial year of adoption. The Company adopted ASU No. 2016-02 as of January 1, 2019, using the transition method per ASU No. 2018-11 issued in July 2018 wherein entities were allowed to initially apply the new leases standard at adoption date and recognize a cumulative effect adjustment to the opening balance of retained earnings in the period of adoption. Accordingly, all periods prior to January 1, 2019 were presented in accordance with the previous ASC Topic 840, Leases, and no retrospective adjustments were made to the comparative periods presented. Finance leases were not impacted by the adoption of ASC 842, as finance lease liabilities and the corresponding ROU assets were already recorded in the balance sheet under the previous guidance, ASC 840. The Company elected the package of practical expedients permitted under the new standard which, among other things, allowed the Company to not reassess the lease classification, the lease identification and the initial direct costs for any existing leases. Further, as permitted by the standard, the Company made an accounting policy election not to record ROU assets or lease liabilities for leases with a term of 12 months or less. Instead, consistent with legacy accounting guidance, the Company will recognize payments for such leases in the consolidated statement of operations on a straight-line basis over the lease term. Upon adoption on January 1, 2019, this standard resulted in the recognition of additional assets of $3.2 million and liabilities of $3.3 million on its accompanying condensed consolidated balance sheet. The new standard did not have a material impact on the Company’s results of operations or cash flows. In August 2018, the FASB issued ASU 2018-13, Disclosure Framework—Changes to the Disclosure Requirements for Fair Value Measurement. This amendment removes, modifies, and makes certain additions to the disclosure requirements on fair value measurement. The amendments in ASU 2018-13 are effective for fiscal years beginning after on December 15, 2019 and interim periods within those fiscal years. The Company is currently evaluating the impact that the adoption of this new standard will have on its consolidated financial statements.
Revenue	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, Icebreakers, Flash! and Shout! (collectively, the “In-App Products”). Users purchase the In-App Products to exchange for the Company’s virtual products. The In-App Products allow users to engage with other users on the applications and in live video. They also 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 In-App Products but have a limited right to use the In-App Products on virtual products offered for sale on the Company’s platforms. In-App Products may be used to purchase virtual gifts for other users. These virtual gifts are received by other users and converted into Diamonds. Diamonds represent an intermediary currency that the Company manages. Diamonds can either be converted back into credits or may be used to claim rewards, including in some instances cash rewards. The In-App Products are not transferable, cannot be sold or exchanged outside of our platforms, are not redeemable for any sum of money, cannot be gifted to other users and can only be used on our platforms. The In-App Products are recorded in deferred revenue when purchased and recognized as revenue over time when: (i) the In-App Products are used by the customer; or (ii) the Company determines the likelihood of the In-App Products being redeemed by the customer is remote (breakage) and there is not a legal obligation to remit the unredeemed In-App Products to the relevant jurisdiction. The breakage rate is based upon Company-specific historical redemption patterns. Breakage is recognized in revenue as the In-App Products 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 (loss). Breakage recognized during each of the three and six months ended June 30, 2019 and 2018 was $0.9 million and $1.6 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 Product purchases are satisfied by standing ready to allow users to exchange the In-App Products 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. 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 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 is such that the Company provides 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 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.
