OMG you all make me feel ancient! let's just say I'm 21 and a bit (the bit is getting very large) and I've watched Star Trek since it first aired, 6pm on Wednesdays was sacrosanct in my house and BBC2 was king. no pause, +1 channels or repeats in the early days so no interuptions or distractions were tolerated.
Life is easier nowadays and the first wish list entered into my Tivo when I got it was anything containing Star Trek in the title :)
I love that so many young people also love ST.
