Zynga to File for IPO on Wednesday

Zynga, the company that makes FarmVille and other social games, is the latest Web company to jump on the IPO train: It's expected to file for an IPO on Wednesday that could raise from $1.5 billion to $2 billion. That would put the company’s total valuation from $15 billion to $20 billion—which is more than the two biggest videogame publishers, Blizzard Activision and Electronic Arts, combined. The company, unlike many tech companies, has a steady revenue stream: A few months ago, it was estimated to bring in about $1 billion each year, largely through in-game amenities and purchases.
