From The TV IV
Series can have different meanings:
- In the USA (and other countries), a series is another term for a program (e.g., Battlestar Galactica is my favorite series).
- In the UK (and other countries), series refers to a year's run for a particular program (e.g., The fifth series of Cheers was better than the sixth, because Shelley Long was better than Kirstie Alley). In the USA, this is referred to as a season.
- In French, the term série refers to a program with mostly independent episodes (e.g., CSI) in contrast to feuilleton, which designates a serialized show that tells an ongoing story in contiguous installments (e.g., Lost, soap operas, typical miniseries).
