Clickz reported that Ringleader Digital, a firm focused on behavioral advertising for mobile devices, may have ceased operations and closed without notice:
"Its staff is no longer answering or returning phone calls and emails... A doorman in the lobby at the address listed on Ringleader's corporate website - 286 Fifth Avenue, New York, NY – said the company's offices have been locked since the beginning of the month and no one has entered the premises since..."
Ringleader's technology was the focus of concern by several privacy advocates. The company faced several class-action lawsuits for allegedly performing tracking and data collection of mobile devices without providing notice to users nor gaining users' consent. The two major class-action lawsuits were Hillman et al and Aughenbaugh et al filed in November 2010.
The Hillman complaint included as codefendants several well-known companies: Ringleader Digital, Accuweather, CNN, ESPN, Fox News Network, Go2 Media, Merriam-Webster, Travel Channel, and the Whitepages. ESPN and Fox News were not listed as defendants in the Aughenbaugh complaint. The Hillman complaint alleged that Ringleader's mobile tracking violated the mobile device manufacturers’ agreements, and included the tracking of minor children.
According to ClickZ, Ringleader had agreed to settle out of court one of the lawsuits.
