Market index shows Calgary, Edmonton being the most competitive radio markets

Earlier this week, we looked at the share in hours of each media company in the largest markets in Canada. Using those same share totals, we can figure out how concentrated or competitive the Canadian radio markets are.

In each city or market, the shares of all media companies, not the stations themselves, like Astral, Bell, CBC, Corus, and Rogers are added. One would expect the result to be 100%. However, this isn't the case since community/campus radio stations don't participate in the studies and neither do ones from other markets that happen to be picked up. (As a reminder, the share is calculated by taking the the number of hours tuned to a particular station, or in this case the media company, and dividing it by the total number of hours listened to the radio.) So, the problem with using the share values from the BBM data is that we also have to include the other radio stations that help sum all the shares to 100% and we don't have that information.

More Ottawa radio numbers (Fall 2012)

With the BBM ratings of Ottawa radio stations released last week, Canadian Media Ratings reported the numbers, but we wanted to do more with the data. Ottawa-Gatineau has a wide range of radio stations, close to the same number as the Greater Toronto Area. Since the nation's capital is being served by many different radio stations, the market is very competitive. The following shows the total number of hours of Ottawa-Gatineau Anglophone listeners split up by media company:

Ottawa Fall 2012 radio ratings

BBM has revised its bi-annual Ottawa-Gatineau radio ratings from earlier this morning. The Fall 2012, September 3 - October 28, numbers are market shares of Anglophone listeners (in percentage):

BBM defines "share" as "Within the central market area, the estimated total hours tuned to that station expressed as a percentage of total hours tuned to all radio."

Other BBM notes: Timeblock: Monday-Sunday 5am-1am. Demographics: A12+.
