Google's purchase of Youtube will be interesting to watch from several points of view. Will they be able to establish internet entertainment as a mainstream trend? Will they be able to bring in their advertising expertise to make Youtube profitable? Will they bring in more copyright material rather than the large volume of home made videos presently online? If they do, will they lose their present customer base? Google is incredibly innovative, to be sure, but not everything they do makes money. In this case, they seem to be latching onto a major trend, one that has the potential to change the very nature of television, perhaps even make conventional television obsolete. But how long will this take? And what business models will make it happen? The Google venture will help us to address some of these questions. globeandmail.com: Google takes a lead in the on-line video revolution
