Having already seen the first season of Torchwood, I haven't caught it's North American debut on the CBC.
That didn't stop me from visiting the CBC to see what they are doing to promote it. Let's just say we shouldn't have complained about the lack of promotion of season 2 & 3 of Doctor Who.
What caught my eye was that Torchwood seems to be broadcast in HD? I just might have to get my sister (who has a HD tv and satellite box) to PVR an episode so I can see how nice it looks in HD.
On the Doctor Who front, the CBC is streaming the last three episodes of series 3 online at their Doctor Who mini site. So if you want to catch some Who legally visit the site. If you're outside of Canada I don't know if there are any restrictions to viewing them (as the BBC site often does on content). At least it looks better than YouTube.
