Netflix tried something similar a few years ago, but in my opinion it missed a critical ingredient, which was dropping people into the middle of content at a compelling point.
Really like the execution here. YouTube take note.
We did a mix of human curation and random selection, noting which random selections were successful and which were not. It was effective enough. The thing about an experience like this is that it doesn't need to be perfect. Like channel surfing, if it doesn't catch you then just switch the channel.
