[Air-L] Marxist Critiques of Online Advertising?

Anybody know of any Marxist critiques of online advertising? Anything looking at Pagerank and YouTube advertising through the frames of monopolisation, commodification, and accumulation? Des Freedman has an excellent starting point in Web 2.0 and the Death of the Blockbuster Economy in Misunderstanding the Internet. Anything else? Thanks.
