On July 12, 2006, Microsoft launched the "Xbox Live Arcade Wednesdays" program, which promised a new Arcade game to be launched every Wednesday for the rest of that Summer. When that summer ended, Microsoft announced that new titles for XBLA would also be released on Wednesdays. In order to promote the service in retail, Microsoft released "Xbox Live Arcade Unplugged Volume 1" as a compilation disc of six games. On October 18, 2007, Microsoft announced the Xbox 360 Arcade console SKU which includes full versions of "Boom Boom Rocket", "Feeding Frenzy", "Luxor 2", "Pac-Man Championship Edition", and "Uno". On May 22, 2008, Microsoft's general manager of Xbox Live, Marc Whitten, detailed changes for the service that included increasing the size limit of the games to 350MB and improving the way digital rights management is handled. Furthermore, Microsoft created an internal games studio to create "high quality digital content" for XBLA.
