Is 电视剧 equivalent to "TV series" or "TV drama"? https://www.quora.com/topic/Television-Dramas

I find TV dramas only refer to Chinese/Japanese/Korean 电视剧 on the quora topic. Why?

English 电视剧 only are called TV series?
If an English 电视剧 only has one season, can it be called series?
「電視劇」is equivalent to TV drama.「電視劇」does not tell you anything about the length of the series (if there even is a series) or the number of seasons in the series.


  If an English 电视剧 only has one season, can it be called series?


Yes. A TV series represents a connected group of TV shows with the same title/name. Series are only divided into seasons because of traditional American TV airing practice, where half the year is devoted to viewing and the other half is a re-run.

TV dramas are a product which responds to supply and demand; by nature, if a TV series is not performing by popularity metrics, then there will be no contract to make another season in the series. There are many single-season TV series out there (for various reasons, not only due to lack of popularity).

A TV drama series is called「連續劇」in Chinese. Dramas, in general, are just called「戲劇」, so you can get single "episode" (more like a mini-film) dramas called「單元劇」.
