Texas goes after Google -

The Lone Star state, Texas, is asking Google to give it an explanation of how it charges for adverts after locals complained that it indulged in antitrust behaviour. It doesn't just want answers on that particular matter.

The Texas Attorney General has demanded a whole raft of documents from Google and wants answers to a number of questions.

Those include not only its ad rates, but whether it manually overrides or changes search result rankings. As well as these demands, it wants information from Google about Yahoo and Bing.

It wants Google to tell it all about its own shopping sites including Google Shopping, Google Product Search and Google Froogle.

The US Justice Department is currently pondering whether to give Google the go-ahead to buy airline ticket firm ITA Software.
