This is just a question purely out of curiosity.

How far behind the USA was the UK when it came to the original screenings of Dallas ?

I loved Dallas first time round as a kid but I've really got back into just lately with the DVD releases and was just intrigued as to how far behind our screenings were here. I'm guessing not too far as big cliffhanger resolutions such as Kristin shooting JR and Bobby coming back to life in the shower were presumably not spoilt before the episodes premiered in the UK. Of course this was pre-internet I know but surely once word was out in the US it would have spread, all be it a slower pace than today.

Any answers would be much appreciated.
