Use of "showrunner" attribute for producers - when/why/WTF?
Maybe the term "showrunner" means something to some people. Maybe it's more of a US than UK thing. I've never heard of it before. Is it a term that is used more within the TV industry than in general parlance - like some sound crew who are credited on-screen as "sound recordist" (general parlance) are listed in IMDB as "production sound mixer" (TV/film industry jargon)?
When should "showrunner" be used? If a producer is listed in the credits as (for example) producer or executive producer, and someone has already added a "showrunner" attribute in the IMDB entry, should this remain or should it be deleted if it does not appear in the on-screen credits? Is it a case of inside knowedge: happening to know that someone is a programme's showrunner even if they are not credited like this on-screen? Is it an exception to IMDB's normal policy of "transcribe it as it is shown in on-screen credits"?
