NB (TV show)
NB was a television series about the arts that was launched in 1989 and was shown in Scotland until it ended in 1997. Produced by Scottish Television, it was largely conceived by its producer Donny O'Rourke, and presented by a young, all-Scottish cast. Daily Record television critic Paul English wrote that the show "helped shape the taste of Scotland's clubbers, gig-goers, opera lovers and theatre-buffs too".
