The One Network was 38 regional radio licences, trading under one umbrella, that was rebranded as Heart in 2009 (see here).

What it was and what it became is largely irrelevant as this is a quick post about a job offer that never came to fruition (so far as I can tell).

I think the first story came from Radio Today (here) who announced (March 27^th 2008) that GCap Media (who owned the Network) had hired Jimmy Carr to host a networked programme.

That same brief announcement was then repeated by The Mirror (here), although they said that the group of stations totalled 42.

Forums on Digital Spy (here and here) debated whether it may happen.

Ultimately, I can find zero evidence that anything ever came of it.
