Google confirms FTC probe

Google confirmed on Friday that the Federal Trade Commission is investigating it but says it's not sure why.

On Thursday, The Wall Street Journal reported that FTC had subpoenaed the Internet-search giant as the start of an antitrust probe.

"Yesterday, we received formal notification from the U.S. Federal Trade Commission that it has begun a review of our business," Google said in a blog post.

"We respect the FTC's process and will be working with them (as we have with other agencies) over the coming months to answer questions about Google and our services," the post said.
