There are no prizes for guessing the most popular (and sought-after) types of internet enterprise at the moment. Anything that can be labelled Web 2.0 – social networks such as MySpace and Facebook, news aggregators such as Digg and Reddit and user-generated sites such as Wikipedia and Flickr – are the new new media.

Facebook is the latest such company to think of selling itself, with companies such as Yahoo and Viacom being asked to cough up $1bn (£526m). With News Corporation’s purchase of MySpace last year for $580m now being regarded by Wall Street as a master stroke, other media companies are trawling for their own Web 2.0 acquisitions to transform themselves in the eyes of investors.
