I think the problem is that until recently, the costs of producing and distributing these videos was much higher. With the rise of YouTube, it has become possible for a Salman Khan or John Green to become a celebrity eduvideographer without a lot of capital investment. One of the flaws of common core is that it seems that the proponents did a poor job of marketing it to the broader adult community. Doing so would have: 1) Given parents the answer to "why is this change happening at all? I learned math just fine as a kid!" 2) Engaged some people in trying to think about the best ways to explain that material and accelerated the formation of a community that gains status with each other by coming up with better and better explanations of the common core curriculum.
