Oh, for God's sake. I think there's a bit of a difference between expressions like 'on the record' or '(the) line of duty', which most people will be aware of, and 'outside source', which is pretty meaningless.

But there really isn't. It's a name of a television programme - that's all it is. Some people might not like it, but the objective is to be a bit distinctive and I would say that Outside Source is more distinctive than most other names of news programmes. It doesn't really matter if I entirely get the reference, which is actually reasonably self-explanatory, just as there isn't the need for me to be fully aware of the source material for the literary allusions of the names of hundreds of episodes of TV dramas.

Is Outside Source the right name for a programme that (these days) is primarily based on providing context on the day's news? No. Is The Context really a good name for a programme in which contributors from outside the BBC give opinions on the day's news? No. Are they just actually just names for differently formatted strands on a TV news channel? Yes.
