Only when Googleand Overture came along did a really sustainable ad model arrive. Idon't know if it was a right choice or not to wait see you later. Fromthe standpoint of crazy market valuations, it was a bad idea, sinceadvertising gave you this nebulous but large upside, so long as peoplebelieved in it. In addition, people won't admit it, but the ideathat you'll be able to switch enterprise models easily may be false. The moreyou put money into a business model, the harder it is to turn the shipeven if you know the time is good. Tim O'Reilly merits a different point out here, and not just for theearly Viola browser his agency constructed. Tim is essentially abook writer, with the best line of technical books in the unix, linuxand cyber web space. However, he was also keen on internet eBook publishingand began GNN Global Network Navigator as the internet was dawning. Itwas the 1st severe commercial web site, with a plan to be advertisingsupported. He sold it to AOL for a good price at the time. If yourdefinition of the first dot com depends upon it being HTML based,O'Reilly and Associates and GNN.
