What is Savanna Principle

Video games are a relatively recent form of entertainment whose sales growth has been enormous (almost 700% from 1996 to 2007), with sales for 2007 reaching 9.5 billion dollars in the US (Entertainment Software Association, 2007). This figure does not include the sales of hardware components such as consoles and accessories, or subscriptions to high-speed Internet providers. To contextualize this sales figure, the US cinema industry garnered 9.6 billion dollars domestically in the same year (MPAA, 2007). The video game industry is so robust that it appears to be impervious to the current economic crisis (Economist, December 20, 2008).
