I think I must be coming down with something because what WJ is saying makes complete sense to me. Sure most people aren't coming home from work on Saturday night but the 5:30 time slot still isn't great. I struggle to watch games then on a Saturday as I have kids to deal with and a lot of people that play rugby on the weekend or watch club rugby might not be home to watch the game. If the Reds are playing at 5:30 and the Tah's at 7:30 I am more of a chance of watching the Tah's as the time suits me better. It would have been better to compare the viewership of the teams in the same time slot.
Jets: IMO, this point would take some specialist TV sports scheduling analyst to really figure out. However, it would seem to me that the possible smaller natural NSW rugby-watching group at 5:30pm Saturday (smaller vs a 7:30pm NSW group) would be fully cross-compensated for by the fact there are, on paper, far more NSW watchers you would imagine for a Tahs match than for a Reds match. And NSW/Sydney has a far larger base population than Bris/QLD (thus the ARU's love of annual Sydney ANZ Bleds, right?, vs once every 4 yrs in Bris), so that makes the same point another way, and adds to it. So, on the most conservative basis, if this intrinsic-popularity-of-2011S15-team point as per this article was not valid, you would assess that the NSW S15 viewers at 5:30pm would, at the very least, be the numerical equal of QLD S15 viewers at the (maybe) more popular 7:30pm slot. But, according to this article, they weren't equal at all, they were materially lower. Thus, as a non expert in all this, I think the article's conclusion re the Reds taking major 'rugby TV viewer share' from the Tahs/NSW is probably still valid.
But I was more attracted to this (more strategically significant) part of the article highlighting an S15 rugby match catching up v close to prime League and AFL matches:
Sunday's hard-fought victory over the Crusaders attracted an average viewing audience of 202,000, making it the second highest rating Super Rugby clash of the season behind the first game of the new Rebels franchise against the Waratahs, which attracted 231,000. The match was the third highest rating television program on Fox on Sunday behind the Storm-Sharks NRL match (233,000) and the Western Bulldogs-Hawthorn AFL game (214,000) but comfortably ahead of the Brisbane Lions-Adelaide game, which attracted 134,000.
