They didn't demand it per se because no one actually asked. I'm inferring from the fact that users spent much more time on the interactive websites which resulted in more revenue for those sites and everyone else copying. There might have been a reason other than the interactivity itself, but we are where we are now because of user behaviour.
How efficient was that increased time spent? Does the user actually read more text or are they spending more time just fighting with the site layout? I guess the answer doesn't matter if there is an ad on the page.
