On Rush's show there isn't one second more of commercial time than 10 years ago.
However, a couple years ago it was discovered that some radio stations were using a "secret" technology that compressed shows by eliminating any spots of dead air and by doing so they could squeeze in over an additional minute of commericals per hour. Can't remember what it was called.
I'm not saying its any longer, I'm just saying I can't take it anymore.
I think it's called CashBox.
Great article by this Zeiger kid.
