Depends on what you mean by 'awash'. The Net is the first completely uncensored publication medium in history so you'd expect it to carry porn. So although there is porn on the Net, it is swamped by all the other stuff on it. You'd never gather than from reading the tabloid press though. Wrong, wrong, wrong.
Television is a 'push' medium.
And because it's so easy to publish on the Web, the range of choice is unimaginably diverse. The Net is an active medium, whereas television is passive.
