Also revealed in the video game survey cornucopia are SBGs, an acronym that – while never broken down (server-based gaming?) – is defined as "programmatic, highly concurrent social interactive games." Again we see Microsoft aiming for that mainstream audience. With SBGs, you'll be able to use Xbox Live to "browse, discover and download" games ranging from game shows (they use "Jeopardy" and "Who Wants to be a Millionaire" as two examples) to trivia to reality TV to puzzles to fantasy sports leagues.
One of the most interesting aspects of the model is the "programmatic" part – the content can be programmed to coordinate with special events (think Super Bowl or Oscars) and, because it's "highly concurrent" you'll be playing against "massive" groups, not to mention people in the living room with you. It certainly sounds like an ambitious program and one that would leverage the Xbox Live infrastructure to provide something besides a couple rounds of CoD4.
