Investments [Abstract]
Investments	The Company’s investments at September 30, 2018 and December 31, 2017 consisted primarily of investments in SaleMove and GoMoto, Inc., a Delaware corporation (“GoMoto”). In September 2013, the Company entered into a Convertible Note Purchase Agreement with SaleMove in which AutoWeb invested $150,000 in SaleMove in the form of an interest bearing, convertible promissory note. In November 2014, the Company invested an additional $400,000 in SaleMove in the form of an interest bearing, convertible promissory note. Upon closing of a preferred stock financing by SaleMove in July 2015, these two notes were converted in accordance with their terms into an aggregate of 190,997 Series A Preferred Stock, which shares were previously classified as a long-term investment on the consolidated balance sheet. The Company recorded an impairment charge of $0.6 million in SaleMove in the three months ended December 31, 2017. On, June 5, 2018, the Company sold its shares of Series A Preferred stock back to SaleMove for $125,000. The gain of $125,000 is recorded in Interest and other income (expense) on the Unaudited Consolidated Condensed Statement of Operations and Comprehensive Income (Loss) for the nine months ended September 30, 2018. In October 2013, the Company entered into a Reseller Agreement with SaleMove to become a reseller of SaleMove’s technology for enhancing communications with consumers. SaleMove’s technology allows Dealers and Manufacturers to enhance the online shopping experience by interacting with consumers in real-time, including live video, audio, and text-based chat or by phone. The Company and SaleMove share equally in revenues from automotive-related sales of the SaleMove products and services. In connection with this reseller arrangement, the Company advanced $1.0 million to SaleMove to fund SaleMove’s 50% share of various product development, marketing and sales costs and expenses. These previously advanced funds are repaid to the Company from SaleMove’s share of net revenues and expenses from the Reseller Agreement each reporting period. During the three months ended September 30, 2018, the Company performed a qualitative review of the agreement with SaleMove and, based on several factors related to the trend in operating results from this reseller arrangement and costs being incurred by the Company, the parties agreed to allow the arrangement to expire November 30, 2018, one month earlier than the original expiration date of December 31, 2018. Upon expiration of the Reseller Agreement, the remaining outstanding advances are no longer recoverable from SaleMove, and, accordingly, the Company has impaired the remaining balance of $364,000 of advances due from SaleMove. The impairment charge is included in “Long-lived asset impairment” in the Unaudited Consolidated Condensed Statement of Operations and Comprehensive (Loss)Income for the three and nine months ended September 30, 2018. In December 2014, the Company entered into a Series Seed Preferred Stock Purchase Agreement with GoMoto in which the Company paid $100,000 for 317,460 shares of Series Seed Preferred Stock, $0.001 par value per share. The $100,000 investment in GoMoto was recorded at cost because the Company does not have significant influence over GoMoto. In October 2015 and May 2016, the Company invested an additional $375,000 and $375,000, respectively, in GoMoto in the form of convertible promissory notes (“GoMoto Notes”). The GoMoto Notes accrue interest at an annual rate of 4.0% and are due and payable in full upon demand by the Company or at GoMoto’s option ten days’ written notice unless converted prior to the repayment of the GoMoto Notes. The GoMoto Notes will be converted into preferred stock of GoMoto in the event of a preferred stock financing by GoMoto of at least $1.0 million prior to repayment of the GoMoto Notes. At September 30, 2018 and 2017, both the GoMoto Notes and related interest receivable are fully reserved on the Unaudited Consolidated Condensed Balance Sheets because the Company believes the amounts are not recoverable. Further, the three months ended September 30, 2018, represented the third consecutive quarter of declining operating results for GoMoto and, as such, the Company performed a qualitative review of its investment in GoMoto. Based on continuing deterioration in GoMoto’s financial position, the Company believes that uncertainty exists in the recoverability of its remaining investment of $100,000 in GoMoto and, accordingly, recognized a loss on the investment during the three months ended September 30, 2018 which has been recorded in “Interest and other income (expense)” on the Unaudited Consolidated Condensed Statement of Operations and Comprehensive (Loss)Income for the three and nine months ended September 30, 2018.
