Our mini-series about the internet continues. This week we take a close look at the fundamental business model of the web – advertising. In 1993 your host was a founding member of an international monkey wrench gang that fought billboards in outer space. He recently ran into one of his old comrades in Midtown-South (Manhattan’s tech district) and discovered that his side actually lost the war. Ethan Zuckerman, the man who invented the pop up ad, admits that we must rethink the fundamentals of the web, and activist, writer, and filmmaker Astra Taylor questions whether the internet actually benefits independent creators.
