it's a huge market-
"According to a study last fall by Information Solutions Group, 42% of Internet users in the U.S. had played a social media game in the previous three months, up from 28% a year earlier. Social media game publisher Zynga Inc. said daily users grew to 54 million in the fourth quarter of 2011, up 13% from the same period in 2010.
"They are clearly the hottest or fastest growing sector of the video game market," said Garth Chouteau, a spokesman for Popcap, a software company and publisher of Bejeweled Blitz and Zuma Blitz. "It is a phenomenon of sorts. You have hundreds of millions of people playing these social games on a regular basis. There was no playing social games four or five years ago."
