I thought it made sense to bundle 'radio' and 'drama' since alot of stand-alone dramas are released on CD only but some were in fact aired on radio/internet before they got a CD release.
However, I always thought this category did not include TV dramas which would need a category of their own. Well, until I saw the all the Ichirou Nitta submissions.
With the increasing amount of anime I would like to urge the addition of more than just one 'video' category, too. TV series (TV Anime/TV Animation), OVA (Original Video Animation) and Movie/Film for the anime part is needed since there are enough releases that have got the same name. And I'm not fond of the idea to put OVA in the title like it was done
here.
