Steam briefly had a content deal with Lionsgate, but the partnership didn't work out (very few sales) and they abandoned the idea of selling TV/Films soon after the partnership collapsed. They didn't seem able to get interest from any other studio in that time, either. (Plus they were not able to and disinterested in supporting the industry standard Movies Anywhere mutual-DRM-unlocks-assurance system, so for at least some consumers their attempt was DOA from the start.)
