They still use people meters. The households each take part for I think a three year term. I guess catch up views get counted from their respective website data. So if you don't have a people meter or use web catch up, it you won't have any effect on the ratings whether you watch it or not.
I think 10 made a mistake in not having any way to tap into the online community for this show. They blanked giving Survivor Oz access, even though that podcast had built a large audience for survivor.
They should have the contestants out doing interviews and the host doing post show wrap ups. As an American, it's odd not to see loads of articles and podcasts and blogs about the show because we get a lot of fan content. For the US show there are 4 weekly podcasts that are quite popular and several others with smaller audiences. There are also several exit interviews with magazines and blogs from the contestants including one with the host.
This show is really good. My fear was putting it on 3 nights would be a mistake because it becomes too familiar. Guess we will see what happens.
Hopefully last nights twist will be enough to attract some more viewers! It's doing well in the demos and online. The positivity fans have been emiting should keep the producers pleased for now in Australian Survivor's early weeks.
