Category talk:Documentary radio programs

Is this category needed?
I'm a bit confused as to why this category is needed in addition to Category:Radio documentaries. If I understand the distinction, if a radio show tells one story, it was classified as Category:Radio documentaries, but if it tells multiple stories, it was classified here. Is that right? If so, then I think the two categories need better names to make this relationship clear. DougHill (talk) 20:44, 6 December 2010 (UTC)
 * I agree that a rename might be a good idea, Perhaps using "series" in the title might make it clearer that this is about weekly or regularly broadcast programme, with different content in each episode, as opposed to a single, one-off radio documentary.
