Truthiness: Obama is Kenyan and Gawker is Too Rich

I'd like to thank Gawker for providing this funny clip (somehow
viewable in Canada) of Colbert explaining the silly election season
and the appeals to the fringe vote.

Two questions:
-How does Gawker get permission to post this (if they do)?
-How do they make their money (I don't see any advertising)?

In Canada, you can watch the entire Colbert report on CTV, Comedy
Network and their respective web sites. In the USA on Comedy Central
channel and, I think, Hulu.
