Searching on Google I found this blog with ratings for ESPN and ESPN 2 for July 22 to 28th. What's interesting for CFL fans is that for ESPN down at ranking 19 there's the CFL (on a Thursday) with 273,000 viewers for three hours. In case you're curious that was a game in Montreal against Edmonton that was won 32 to 27 by the Alouettes.
Those aren't bad numbers, especially considering that ESPN 2 doesn't seem to have a lot of live sports during the summer. Considering that I posted yesterday that last week's Canadian CFL rankings were around 900,000 that's encouraging.
Since the Canadian television deal is around $40 million, could a US television deal be worth $12.3 million proportionately (assuming the $40 million for 900,000 per game versus 276,000)? Probably not, although with rumours that the CFL gets almost nothing for its games shown in the US, they're clearly worth something if shown on a channel with good availability in the US. I haven't seen ratings for the CFL on the the NBC sports channel although they may be lower as the channel is fairly new.
I actually found the blog on this forum, where they make the point that the ratings are higher than MLS on ESPN 2, which is kind of amusing. The forumers make the point that Americans love football and with the first half of the CFL season occurring during a football deficit, the CFL really needs to capitalize on it. Imagine the ratings if Tim Tebow showed up.
