Tapulous, Inc. was an American software and video game developer and publisher headquartered in Palo Alto, California. It was a wholly owned subsidiary of The Walt Disney Company as part of Disney Interactives Disney Mobile unit. The companys most profitable products were the Tap Tap series of music games, which surpassed thirty-five million downloads. Tapulous was founded in February 2008 with the specific intention of developing software applications for the iOS platform. The companys Tap Tap Revenge gained at least one million players in less than one month of availability, and was the most-downloaded free game of the App Store in 2008. Building on the success of the game, Tapulous then heavily focused on the Tap Tap Revenge series by expansion and partnership with Universal Records. As of December 2009, the companys sales totaled nearly $1 million per month. In July 2010, the company was acquired by The Walt Disney Company. On January 9, 2014, the company shut down and removed all its remaining games from the App Store. With the advent of unofficial applications being distributed across the internet, Apple announced the availability of a native SDK for the iOS/iPhone platform in October 2007.
