Sacred Road - TV's First Machinima Series?

This new series (Sacred) is being unveiled at GDC (Variety). Produced by Blockade (co-owned by Gearbox) and utilizing the Brothers In Arms engine, it will be an animated series shown on GamePlayHD.

Will this just be an extended advertisement for BiA or a real piece of animated storytelling? Is this the first machinima series to be shown on TV (I don't think My Second Life has aired yet?).
