Hulu.com has been making very decent revenue from its business model of putting premium professionally produced content on their website. ABC, FOX, and NBC shows are all available on Hulu.com. It’s definitely no YouTube.com so don’t mix those 2 up.

Why we think it’s a good model? Well it takes the on-demand model of TV but makes it so much more accessible (on your iPhone, mobile phone, computers and even your TVs as long as you’ve got an internet connection or computer hooked up to it). It’s searchable and real-time so it allows you to really pin point the episode you wanna watch very quickly and easily.

No surprise why people are willing to pay for it.
