One of the great things of financial journalism is that you often have a chance to take a mainstream story and give it an Wall Street spin. Don Imus has been suspended for two weeks at CBS — and MSNBC just went on to can his simulcast forever tonight — so what is there to write about? I took it to the next logical step. Imus will find his way on to either XM or Sirius Satellite Radio. It’s only a matter of time, so I wrote about it and its implications.
