The 150 Sesame-related titles most likely refers to all the home videos they've already made.We had kinda known already, both the Amazon and Barnes and Noble pages for the next video, Elmo's World: Elmo Explores, list Shout! as the video distributor. It's odd that there wasn't an official article announcement until after.
I'm curious about the "150 Sesame Street-related titles". At first I thought it meant 150 productions made by Sesame Workshop (but then again I don't think SW has produced that many domestic shows), but it probably refers to all the international co-productions, though I thought it said that the rights were limited to North America (what would be the chances of international co-productions, particularly ones that dubbed the languages, getting released? Though I believe Plaza Sesamo DVDs have been released here).
I wonder if that would count Sesame Street specials and existing video releases. I wonder if they're counting short-form series that air as part of the show here (like Elmo's World, Abby's Flying Fairy School, and Cookie's Crumby Pictures) as separate "Sesame Street-related titles". I could see The Furchester Hotel being among those, and Play With Me Sesame, maybe Sesame English, maybe Shalom Sesame, maybe Sesame Park.
Each of the three Old School volumes were released when a different company handled the video rights. If Shout! put out volume four (or if Shout! never does but the next video company to get the rights does, or whatever), then we'd be getting one Old School volume per video distributor.
Shout! is better known for releasing stuff for collectors, which makes it odd that the first Sesame release is an Elmo's World one (though we didn't know of Shout!'s involvement until that was announced). But the last part of the article, saying that they'll be putting out stuff for both today's audience and the generations that grew up with the show, makes it sound like there are collector sets planned (it also mentioned video on demand and Blu-ray, which seem like something more for the collectors).
I did look at the Sesame Street Videography page and counted all the video releases (both direct-to-video, releases of full episodes, and releases of specials) that have been released on DVD (not counting things that wouldn't be included, like the two movies) and only counted 144 releases. And the main Sesame Street Videography page doesn't list Elmo's World or Play With Me Sesame releases (those have a separate videography page).The 150 Sesame-related titles most likely refers to all the home videos they've already made.
I've been thinking the same thing! Definitely more worthy of an anniversary release than that other 1978 SS Christmas special...Something I thought about: Wouldn't it be great if Shout! put out a special edition release of Christmas Eve on Sesame Street this year, to celebrate the specials 40th anniversary? So maybe the anniversary won't get any official acknowledgement or merchandise, but would make for a cool release. I wonder if Warner Home Video would have done such a release (WHV seems to be very fond of rereleasing Christmas productions it has the rights to on multiple releases in various ways).
