In case there was any doubt how far advertising on the Internet has to go, consider that The University of Phoenix is the single largest brand advertiser on the Internet (with some $20m in monthly spend, which is pretty minimal in the context of brand ad spending) and that Internet advertising per household (dollars spend on online advertising divided by total US households) was $288. Compare that with $818 on newspapers (or just over $1k on "direct telephone") (sourced from Mary Meeker's TechTrends June 2008).&160; We've got a long way to go, baby!
