A few weeks back, in advance of Ad Age 's Social Engagement/Social TV Conference in New York, I was talking to Mark Ghuneim, founder and CEO of Trendrr, the social-media monitoring firm. I wanted to know just how much "social TV" -- the intersection of social media and TV -- had grown year-over-year in terms of consumer adoption. Mark ended up presenting some data at SE/STV showing that social activity (including tweets, Facebook updates and check-ins) surrounding broadcast prime-time TV increased by 194% from April 2011 to April 2012 -- nearly quadrupling in volume.
