KevJumba + The Amazing Race = CBS*(CwF + RtB)

I'm a fan of (and have subscribed to) KevJumba on YouTube. Recently, KevJumba and his dad made it onto CBS's TV series The Amazing Race, and KevJumba has made 3 videos out of this so far. The most recent one (which I will embed at the end of this post) details how they almost didn't make it because one of the tasks in the beating Ghanaian sun almost made his dad suffer a heat stroke (so his dad needed serious medical help); I was truly touched by this uncut show of mutual affection and support, and I was happy to see that this round was not an elimination round (more on that later) and that KevJumba and his dad can stay on the show.
Then, after watching the video, I realized something: he has been putting clips (each a few minutes long) of the show in his video. That's copyrighted material. Yet, CBS isn't going after him for it. Now, I don't know if that's because he's using his own footage (but considering that he shoots almost all of his own videos (except when he's collaborating with other people on projects), I don't think he's shooting his own video this time, so this must be footage from CBS), but in any case, CBS isn't going after him for it, and I think that's great.
[speculation] What if CBS decided to be anal about it and send his channel DMCA takedown notices? Well, of course, he would have to comply or risk being sued; the former is far more likely. Keep in mind that while his audience is quite diverse, the largest portion of his viewers is probably of East Asian origin. Many of these viewers probably did not watch the show on CBS prior to his selection to participate in the show; hence, thanks to him, the show now has an entirely new (and quite significant) viewing demographic. If CBS really did send out takedown notices to KevJumba, while there would be a few people who are now interested enough in the show to continue watching, many more would be angered by the removal of the YouTube videos, and not having this alternate avenue for keeping up with KevJumba's progress through the show (because YouTube videos, unlike TV without a DVR, can be watched at any time), these viewers will likely stop watching the show altogether. [/speculation]
But CBS hasn't done this. In fact, I and many other YouTube commenters suspect that this round was made to not be an elimination round on purpose to keep KevJumba and his dad on the show. Why would CBS and the show producers do this? I think they recognize and appreciate the great service KevJumba has done in terms of increasing the size of the audience. Thus, not only has CBS allowed KevJumba to post clips of the show in his videos, but they have kept him on the show specifically to let this continue and thus let the viewers (and, by extension, the money) keep flowing in. In TechDirt parlance, this would be an example of connecting with fans and giving them a reason to buy (CwF + RtB): the CwF is CBS allowing KevJumba to bring viewers in by showing his viewers clips of the show, and the RtB is CBS keeping him on the show, giving viewers a reason to continue watching. Eventually (though this will take a little time), these new current viewers will probably form a more permanent portion of the audience who will enjoy watching the show regardless of KevJumba's presence on the show. Bravo, CBS, for doing the smart thing (so far), and keep it up!
