PopCap Games, the worldwide leader in casual video games, announced the results of a new survey which found large increases in overall usage and frequency of mobile game playing among U.S. and U.K. adults. The survey, conducted by Information Solutions Group, also found that among mobile phone gamers, the mobile phone is now the primary gaming device of choice, leapfrogging video game consoles and personal computers in less than two years. Further, "smartphone" owners (the fastest-growing mobile segment) are by far the most avid consumers of mobile phone games. These and other purchase and consumption trends identified in the survey suggest significant growth in the mobile games sector will continue for the foreseeable future.
