By way of pondering this suggestion that Rogers may take 1130 to Talk, a variation of this has been suggested before in other radio corpse.
One idea is to do the news wheel thing during prime time, ie: 5:30am to 10am and 3pm until 7pm, then do talk with hourly and half hourly news updates while continuing with traffic and weather around the clock.
That way, they could run talk show re-rolls during the overnight period while still keeping the timing.
The talk portions also can generate stories and clips for the news wheel segments with followup interviews.
680 News is doing very well in Toronto.
News 1130 shows slow but steady growth here.
Again, the problem for all news and/or talk radio is cost.
A bunch of people, even at ten bucks an hour, cost a lot more than a computer pumping out the same 300 tunes 24/7.
