Shares of Facebook (Nasdaq: FB), the No. 1 social network, opened higher in Wednesday trading. They rose 47 cents to $29.25 at the open.
Shares rose despite the request by the U.S. Federal Trade Commission for more material about Facebook's plans to acquire Instagram, a photo app developer, for cash and stock valued at $1 billion.
The deal was negotiated last month by Facebook CEO Mark Zuckerberg and Instagram's Kevin Systrom. An Israel financial site reported Facebook might also acquire face.com, a facial-recognition site, for about $4 million.
