According to a story on the BBC business site today, the answer is Undoubtedly yes.
Here's a taste of the article:
"On Tuesday, Radio 4 starts a new series called A Small Business.
There's no better time to be hearing from people who have been there, done that, survived recession and all those other hurdles at which small businesses sometimes falter, and, in the case of Fran Cotton got the rugby shirt."
The programme starts at 4pm so you've got 2 hours to find a radio!
