Revenue In accordance with ASC No. 606, revenue from contracts with customers is recognized when control of the promised services is transferred to the customers in an amount that reflects the consideration the Company expects to receive in exchange for those services. Sales tax is excluded from reported revenue. The Company has elected the practical expedient allowable by the guidance to not disclose information about remaining performance obligations pertaining to contracts that have an original expected duration of one year or less. Subscription Revenue The Company generates subscription revenue primarily from monthly premium subscription services. Subscription revenues are presented net of refunds, credits, and known and estimated credit card chargebacks. During the six months ended June 30, 2019 and 2018, subscriptions were offered in durations of one-, three-, six- and twelve- month terms. All subscription fees, however, are paid by credit card at the origination of the subscription regardless of the term of the subscription. Revenues from multi-month subscriptions are recognized on a straight-line basis over the period where the service is offered to the customer, indicated by length of the subscription term purchased. The unearned portion of subscription revenue is presented as deferred revenue in the accompanying condensed consolidated balance sheets. The deferred revenue at December 31, 2018 was $1,468,571, of which approximately $1,150,454 was subsequently recognized as subscription revenue during the six months ended June 30, 2019. The ending balance of deferred revenue at June 30, 2019 was $1,477,367. In addition, the Company offers virtual gifts to its users. Users may purchase credits in $5, $10 or $20 increments that can be redeemed for a host of virtual gifts such as a rose, a beer or a car, among other items. These gifts are given among users to enhance communication and are typically redeemed within 30 days of purchase. Upon purchase, the virtual gifts are credited to the users' account and are under the users' control. Virtual gift revenue is recognized upon the users' utilization of such at the fixed transaction price and included in subscription revenue in the accompanying condensed consolidated statements of operations. Virtual gift revenue was approximately $1,478,239 and $2,899,073 for the three and six months ended June 30, 2019, respectively. Virtual gift revenue was approximately $1,742,423 and $3,752,923 for the three and six months ended June 30, 2018, respectively. Advertising Revenue The Company generates advertising revenue from the display of advertisements on its products through contractual agreements with third parties that are based on the number of advertising impressions delivered. Measurements of impressions include when a customer clicks an advertisement (CPC basis), views an advertisement impression (CPM basis), or registers for an external website via an advertisement by clicking on or through the application (CPA basis). Advertising revenue is dependent upon traffic as well as the advertising inventory placed on the Company's products. Technology Service Revenue Revenue under the Company's technology services agreement (the "ProximaX Agreement") with ProximaX Limited ("ProximaX") is recognized based upon proportional performance using labor hours as the unit of measurement. Pursuant to the terms of the ProximaX Agreement, ProximaX agreed to pay the Company, among other things, up to an aggregate of $10.0 million of cash or certain highly liquid cryptocurrencies in exchange for the Company's services, $5.0 million of which was paid in May 2018, $2.5 million of which was due upon completion the second development milestone set forth in the ProximaX Agreement and $2.5 million of which was due upon completion of the third development milestone set forth in the ProximaX Agreement. The contractual upfront fee was paid in the Ethereum cryptocurrency and subsequently converted into U.S. dollars. The upfront fee also included 216.0 million XPX tokens. The total upfront fee was recognized as revenue under the input method based on proportional performance using labor hours as the unit of measurement. The portion of the upfront fee that remained unrecognized as of the termination of the ProximaX Agreement was $1,631,105 and was recognized as revenue upon such termination. In the second quarter of 2019, the Company completed, and ProximaX accepted delivery of, the work constituting the second development milestone under the ProximaX Agreement. During the final stages of delivery of the second milestone, ProximaX informed the Company that capital constraints made it unable to pay the Company the $2.5 million as stipulated under the ProximaX Agreement. Accordingly, the Company and ProximaX entered into an agreement, effective June 24, 2019, to terminate the ProximaX Agreement (the "Termination Agreement") and provide for payment terms for the $2.5 million due under the ProximaX Agreement. Since there is no assurance of collectability on the remaining payments, revenue will be recognized as the payments under the Termination Agreement are received.
