Shrinking the so-called social TV market, Viggle just bought GetGlue for $25 million in cash and stock. With the deal, Viggle is hoping to establish itself as a “dominate force in social TV,” TheWrap.com reports. “Together, the two companies will have more than 4 million users.” Less than year old, Viggle offers registered users points for loyalty and engagement, which can be redeemed from brands like Best Buy, Amazon, and iTunes.
