In American terms, Friends only had one series because we consider a series the show as a whole. There was a spinoff of Friends called Joey, but it didn't do very well, and I don't know whether or not you want to consider that another series of Friends. I believe that in British terms, a series is one "year," per se, of a show, or what Americans call a season. There were 10 seasons, or series in UK terms, of Friends.
The British sitcom "Porridge," starring Ronnie Barker, originally aired for three seasons from 1974 to 1977. In total, there were 28 episodes produced during these seasons. The show was well-received and has since become a classic of British television comedy. Additionally, there was a feature film and a sequel series, "Going Straight," that followed the original show.
