Not on the subject of Concentration, but it would be interesting to see how the Today Show book treats the subject of Charles Van Doren. Unfortunately there is no video of his Today Show appearances on YouTube.
I can't speak to the newer book, but I have a copy of the last big hardback history the show did (2003) and they not only mention Van Doren and the scandal, they kinda make a big deal about it. In keeping with their mission of patting themselves on the back whenever possible, the focus is on the "extraordinary personal moment" when Dave Garroway addressed the camera to talk about Van Doren's absence. The Garroway speech is quoted at length, maybe in its entirety. I know I've seen the clip before, probably on one of the history specials.
Bit of an off-topic update, as I got a chance to see the current book yesterday, and it turns out they dedicate an entire page to Van Doren, treating him the same way they treated all of the regular contributors. In fact, his listing is even longer than Frank Blair's, the news reader who was with the show for more than two decades. So they don't shy away from Van Doren's contribution even today.
