Back in the WeatherPlus days, WNBC ran 4.4 as a place to throw all their documentary work, occasionally pausing to offer the public the chance to put their short films on the air. One spot that I found pretty funny said it didn't matter which genre..."Drama! Comedy! Dramedy! Documentary! Docu-Dramedy!"
Today's 4.2 is sort of the logical heir to the original 4.4, which was very much branded as "WNBC 4.4". 'Twas a cool branding, but I think New York Non Stop is a better product overall. After a casual Google search, it looks like I never got a chance to experience the period where they coproduced/rebroadcast a number of WNYC/NYC-TV shows in 2006/2007, though.
