Commitments and Contingencies Disclosure [Abstract]
Contingencies	Contingencies In the ordinary course of business, the Company is subject to loss contingencies that cover a range of matters. An estimated loss from a loss contingency, such as a legal proceeding or claim, is accrued if it is probable that a liability has been incurred and the amount of the loss can be reasonably estimated. In determining whether a loss should be accrued, the Company evaluates, among other factors, the degree of probability and the ability to reasonably estimate the amount of any such loss. On October 26, 2018, the Company received a subpoena from the New York Attorney General’s Office (“NY AG”) regarding compliance with New York Executive Law § 63(12) and New York General Business Law § 349, as they relate to the collection, use, or disclosure of information from or about consumers or individuals submitted to the Federal Communication Commission (“FCC”) in connection with the FCC’s rulemaking proceeding captioned “Restoring Internet Freedom,” WC Docket No. 17-108. On December 13, 2018, the Company received a subpoena from the United States Department of Justice (“DOJ”) regarding the same issue. The Company has been fully cooperating with both the NY AG and the DOJ and is responding to the subpoenas. At this time, it is not possible to determine the duration or disposition of either matter. As such, the Company is unable to make a meaningful estimate of the amount or range of loss, if any, that could result from an unfavorable outcome. On June 27, 2019, as a part of a sales and use tax audit, the New York State Department of Taxation and Finance (the “Tax Department”) issued a letter stating its position that revenue derived from certain of the Company’s customer acquisition data services is subject to sales tax, as an information service. The Company believes this revenue should not be subject to sales tax in New York State because it is either an excluded advertising service or an information service not subject to sales tax in New York State, and the Company has responded to the Tax Department outlining this position. The determination as to whether such revenue is deemed a taxable information service and, if taxable, the amount of any taxes owed and the periods for which they may be owed is complex and fact-intensive, and the law in this area is unsettled. Given these uncertainties, the Company believes that it is reasonably possible that a sales tax liability may result from an unfavorable outcome in this matter, but it is unable to estimate the amount or range of any such liability at this time.
