GameJacket

GameJacket was a popular in-game advertising platform used by Flash Developers to monetize and distribute free-to-play casual online games. The service quickly attracted a large following of game developers and within 12 months of launching into beta, GameJacket was delivering 50 million ad impressions each month. Ultimately, the company was unable to secure the 2nd round of funding it needed, which resulted in its closure in June 2009.
