The Federal Trade Commission began an anti-trust probe of various Google services six weeks ago after serving the company with a number of “broad subpoenas”. Today, sources familiar with the proceedings report the probe is now extending to Android and Google’s endeavours in the mobile space.

The WSJ explains:

Six weeks after serving Google with broad subpoenas, FTC lawyers, in conjunction with several state attorneys general, have been asking whether Google prevents smartphone manufacturers that use its Android operating system from using competitors’ services, these people said.

They also have inquired whether Google grants preferential placement on its website to its own products, such as Google’s “Places” business listings, its “Shopping results” or Google Finance services above most other results.

This wouldn’t be the first time government has targeted a technology company expanding into areas other than what they’ve been known for, and it certainly wont be the last. Despite that, Google doesn’t seem to be worried… a Google spokesperson had this to say about the probe:

We understand that with success comes scrutiny”… “We’re happy to answer any questions they (the FTC) have about our business.”
