Official Youtbe Channel?

[Sparktank]

I just did a search on "official youtube channel" and got no results.
What are the official channels on youtube that post official videos?

I don't want fanmade channels or channels like "traileraddict" or whatever.

If I stick to official channels, I won't have to worry about the video ever going offline (unless the owners take down...and not due to piracy issues).

Mostly interested if TF3 has its own official youtube channel.

I thought I found one and subscribed to it, but not all my subscriptions are showing up in youtube.

EDIT: ahhh found one. michaelbaydotcom
It doesn't like it when i use an actual dot ".com"
and it's not one of the top results either.

Are there any other official channels? (i dont count "clevvartv" as a channel)
