> We now pull in recommendations from a wider set of topics—on any given day, more than 200 million videos are recommended on the homepage alone.

What does the first part (wider set of topics) have to do with the second part (number of videos recommended)?

Anyway, YouTube recommendations are generally quite poor I find, though sometimes a few gems come along. I also made the mistake of watching YouTube on my Android TV box. Holy cow, an ad _every single minute_. And the same 4 ads, rotating.
