Rethink "Rethink The Network Economy"

In 2002 Stan Liebowitz stated "...advertising revenues do not have much leeway for further growth, and most sites will need subscriptions to support their content"
When he wrote this comments he referred previously to flaws of a model mimicking over-the-air television.
After reading the announcement of New York Times of forthcoming charges to users to see content, I would partly give up part of reason to Liebowitz in the fact that television model is inadequate.
However, he was wrong in his judgement on limited budget malleability, giving Internet no chance to bite a piece of market share to other media. Eight year later, the fact that Internet Advertising's expenses overtake Television's demonstrated Liebowitz wearies of Internet Advertising effectiveness were unjustified.
Here in Spain, Internet Advertising Expenses grew by 5% percent whilst Television dropped by 23.16% in 2009 against 2008.
Next June 5th I will elicit further about this subject in enaf 2010, in Toledo, Spain.
