Those little intro snippet films that precede BBC shows - what are they called?

[LizzieMacQueen]

I'm trying to google. I know there's a specific name for them but I'm drawing a blank.

Those 2/3 second films for example as part of the intro to BBC's the One Show. I swear I saw my friend in one and I'm trying to find it.

If you know please enlighten me.

Idents?

ident?

I think it's indents

Thank you all. Brilliant. Now i can google.
