FarmVille outfit proves money does grow on trees

Maker of Facebook games Zynga, most famous for its stupidly addictive plant-'em-up FarmVille, is hoping to raise more than virtual crops with its first public stock offering.

The company will file paperwork for the offering today which the company expects to generate more than $1 billion.

The 'appy game maker is looking at more than $1.5 billion in sales this year leading to net income of more than $500 million according to a Bloomberg report.

The company is currently valued at $15.4 billion which would make it bigger than both Activision Blizzard and Electronic Arts.

Not bad for a company which generates most of its income by pretending its games are free, getting people hooked, then refusing to let them progress until they have emptied their wallets.
