Nielsen and NM Insight, a joint venture between Nielsen and McKinsey and Company, has acquired social TV tracking firm SocialGuide. Terms of the agreement were not immediately available. Brooklyn-based SocialGuide has focused a substantial amount of its efforts on Twitter, which has become the de facto home for real-time conversation surrounding television. SocialGuide’s platform tracks conversations around more than 30,000 programs, across 232 English and Spanish-language channels.
