CityVille, FarmVille hit the $10 billion trail
Could these Facebook games really be worth that much?
The paper's Deal Book said the negotiations and high valuation "could further drive investors’ intense interest in social media companies. . . it would also add to the debate over whether the enthusiasm for these fast-growing Internet companies points to an overheated market."
Facebook raised $1.5 billion in January, valuing it at $50 billion. The same month, Groupon closed a $950 million investment round and is thought to be considering a public offering that could value it at $15 billion. LinkedIn, a professional social network, has also filed for an initial public offering.
