Twitter, the king of social TV, geared up recently to capitalize on the second-screen advertising field by introducing an ad API. Now, in conjunction with partner TBG Digital, Twitter has launched a tool that lets marketers bid on ads on Twitter in a similar manner to programming a DVR. Brands simply select television shows along a timeline, and specify demographics or trends they wish to target. This comes in the wake of Oreo’s ground-shaking #blackout tweet during the Super Bowl, which has caused quite a stir in the ensuing months over the future of real-time second-screen advertising via social networks.
