Zynga - interesting statistics

Zynga is all rave nowadays. I was reading an article in AdAge and wanted to share some interesting statistics.

• Top 4 apps in facebook - time spent, are all from Zynga. What is more interesting is that on an average players spent 68 min/day on Farmville and 52 min/day on Mafia Wars! 
• Virtual goods market is slated to be about $2.1B in 2011, however in-game advertising is tiny at $142M today and expected to grow to only $192M by 2011. 
• Nearly all Zynga games play occurs in Facebook and in US (97%).
•  It had 25M UUs in Sept and overall 250M MAU

Wow!
