Take-Two Interactive publishes video games including the Grand Theft Auto and NBA 2K franchises, developed through its Rockstar Games and 2K studio labels, along with a mobile gaming business built through acquisitions of mobile game developers. Grand Theft Auto has been one of the best-selling video game franchises in history, and new releases in the series tend to generate enormous revenue over an extended period following launch. The company's NBA 2K franchise generates recurring revenue not just from initial game sales but from ongoing in-game purchases of virtual currency and content, a business model that has become increasingly important across the video game industry. Take-Two's results can be volatile around major game releases, since a single blockbuster launch can drive a significant share of annual revenue and profit in the periods immediately following it.
