The US Federal Trade Commission is investigating Microsoft Corp's planned acquisition of aQuantive Inc as well as Yahoo Inc's proposed deal to take full control of Right Media Inc, The Wall Street Journal reported on Thursday.
The newspaper, in its online edition, cited lawyers close to the deals as saying that the FTC is conducting antitrust reviews. The FTC already is looking into another online advertising merger, Google Inc's $3.1 billion bid for DoubleClick Inc.
So far, the FTC has not made "second requests" for extra information from either Microsoft or Yahoo, the newspaper reported. Those requests would suggest a closer level of scrutiny. A Microsoft spokesman told the Journal that the company is "co-operating fully" and it looks "forward to addressing any questions the FTC may have."
