On my days not at work I quite often listen to You and Yours (Radio 4). Today they were talking about Google. Today they also mentioned another story that they had covered.
Today it was this: if you search for the name of a well known florist that can deliver to your chosen recipient, among the sponsored links is the name of another one. The first is suing the second. I tried this with the example given (this blog only advertises when I want it to!), and it is indeed so. I have just tried searching for my usual daily newspaper, and it is the only sponsored link that appears. The same happens if I search for the maker of our car.
The other story (which I did not hear and which I can't find quickly on the You and Yours site or in the last couple of programmes on Listen Again) concerned an offensive image of Michelle Obama, which appeared at the top of the list of results. This is reported elsewhere on the BBC, and the report goes into the way that Google ranks results, which of course is all to do with popularity.
