Last weekend's BBC television documentary about Google has been made available online at the BBC site. Don't expect any major surprises, but it is a useful digest of the company's origins, philosophy and business model. It also deals with the issue of click fraud, a potential threat to Google's dominance.

Update: just when we think Google's surprise-ometer has been turned down, it emerges that they have made a deal with the Chinese state to apply filters to their Chinese search engine. At the same time they are under pressure from the US Department of Justice to provide search logs to assist in investigations.
