In case you may not be familiar with VUDU, Wikipedia has an answer. In short, it’s a content provider of movies, shows, and so on. Until now, it was all about buying or renting. Today, VUDU announced free viewing of “thousands” of titles. The only catch is that you will have to watch commercials in exchange. A nice option.
When I was young, a very long time ago, there was a thing called TV. Pretty much the same thing, but the picture is much clearer now. Paid TV, or commercial funded content were the only options back in the day. As it took money to produce decent content, free never really worked out. Turns out, this model still makes sense.
