Not on telly - over the 'net... The show I watched screens on E4 on Saturday night, I've seen (most of) it now so can relax, safe in the knowledge that I'm missing nothing - until Tuesday, when the next episode airs in the USA.
You need a fast connection to be able to view TV on the computer, otherwise it will time out and annoy the hell out of you. I'm on 1Mb cable so it's possible here. I watch via 10 TV WBNS in Columbus, Ohio. (See
http://www.10tv.com/ for info). Also check
http://wwitv.com/portal.htm for a whole list of TV stations, worldwide, you can watch on the 'net.
OK, so I have cable, and can get E4. But E4 is within reach for a lot of people now, as it's on Freeview too - just need a little box to connect to your existing TV set. Seen them on sale as low as £70 in some places.
I know, it's not on 24/7 via Freeview (yet), but you can catch a lot of BB4 USA on it.
