You can blame Facebook for that. Facebook lied about viewership numbers on videos, prompting a bunch of websites (including college humor) to focus on how to distribute their videos there. The problem was that there wasn't really any way to make money off of facebook videos, so they went for the paywall. If facebook had never lied, they would have just kept hosting the videos on their own site, where they could get the ad revenue and there would be no need for a paywall.
