Facebook Inc (FB.O) has begun showing ads on Zynga Inc's (ZNGA.O) website, the first time the company has distributed ads beyond the borders of its own website and raising the possibility that Facebook could eventually launch an online advertising network.
"People may now see ads and sponsored stories from Facebook on Zynga.com," said Facebook spokesperson Tucker Bounds. He said that Facebook does not share information about people or advertisers with Zynga, and that Facebook's advertisers do not have any new "targeting criteria."
