If you were hoping the whole social media craze would blow over and that TV shows would stop putting Twitter handles and hashtags on your big screen, bad news.

Tweets about reality TV shows, sporting events, and comedy programming were the best at pushing people to start watching. Nielsen Analytics vice president Mike Hess says this is vindication for networks that have bought into social media.
