iTunes TV shows, how long do they take to appear after they are broadcasted?

Just purchased the season 5 for Lost Season 5 on iTunes, since it won't start broadcasting in my country for several months and I got tired of chasing each episode through torrents. Any way, if the first episode airs tomorrow Wednesday, when will it be available for download?

Should be up by Friday at least. It's not always consistent.

Ok, hopefully I'll be able to download it by Thursday, I became addicted to that show. Thanks a lot for your replies.
