This is weird.

For the last month, I've been playing a tower defense game called "Kingdom Rush" on my iPhone. I've been playing it night and day, constantly.

Today, YouTube showed be a "recommended channel" that was nothing but videos of levels from the sequel to that game, "Kingdom Rush Frontiers".

OK, so I did a single Google (not YouTube) search, a few weeks ago, about the game's user interface. But I do a lot of Google searches, and I don't get YouTube channel recommendations about all of them.

So, something told YouTube that I need to watch a lot of Kingdom Rush Frontiers videos, just as I'm finishing Kingdom Rush.

Does my iPhone talk to Google ? My iPhone knows my gmail account, but that's not the same as my iTunes account.

Confused. Puzzled.
