Nielsen, the television audience measurement system, is now planning on using Facebook conversations about TV programs in their official metrics. This change is part of a larger effort to gauge how people engage with TV more accurately. The new Social Content Ratings system will also include conversations on Twitter and will cover content on both traditional television and on streaming sites. Sean Casey, President of Nielsen Social said, “Nielsen Social measurement is evolving to provide a comprehensive, standardized picture of how consumers are responding to program content through social media, wherever and whenever.”
