Movie and television mega-database IMDb is adding a new category for Web TV series, Galacticast creator Casey McKinnon says after a conversation with the head of the Amazon-owned site.

“Today there are dozens of web series listed on IMDb, but they continue to be listed as TV Series. At SXSW this year I asked Col Needham, IMDb founder and managing director, for an update in person on whether they plan to start a category for web series.

“The answer is a resounding yes. In the second or third quarter of this year (anytime between April 1st and September 30th), IMDb will roll out the ability to tag a submission as either a web series or an individual (one-off) online video.”

Needham was at South By Southwest Film Festival this week, where he talked about setting a ambitious goal of adding “one-button streaming” for all the titles it indexes. The site already streams some full-length TV shows and movies, along with trailers and other entertainment-related features.

We’ll be interested to watch this new category develop, especially what the qualifiers will be for web video series to be included in IMDb. With thousands of series in production, with a vast range of polish and quality, it will be a challenge to define what is a “real” web series.
