From this post by Laura:
As part of that project, the StackHQ YouTube channel was created. (Yes, that is an "official" SE property.) For a while, we ran a web series called "The Question in Conference Room B", whose purpose was to highlight interesting questions and answers from around the network (not just Stack Overflow) and entertain people at the same time.
We stopped doing that for two reasons:
- The CHAOS project ended and the team disbanded - some members moved into different roles within SE, and some left to explore other opportunities
- It turns out that producing a high-quality web series is an enormous amount of work and very difficult to do well without a large team. The company is growing quickly, but we are not yet at the point where we can afford to invest in our own television department.
So, looks like it's a dead channel.
