I wonder if the sponsors are nervous about this. From my understanding, YouTube sponsors pay based on the number of views a video gets, and if a lot of people are watching the videos to bring the channel up to a billion, that's a lot of money to have to pay Sesame Workshop. And I don't know whether YouTube sponsors pay in dollars or cents.
If only Sesame Workshop could freely use Kermit the Frog, it'd be great if when they got closer to a billion views they did a video with Kermit reporting the progress. Yeah, there's still Telly's "Monster on the Spot" role, and I'll be surprised if any such video is done regardless of who appears. Though wouldn't it be something if the secret video (assuming it's something new) actually featured Kermit?
A thought occurred: What if we still have to wait 44 days for the video to be shown online, even if, say, they reach they're goal tomorrow?
