Facebook for Business is the page you want to read when you are trying to understand how powerful the social network's targeting abilities are. This time: FIFA World Cup. The headline is "the biggest stadium in the world", and they claim to have 49 million soccer fans in the US on Facebook, 62% of them using FB daily "during a recent week". They are more engaged (roughly 1.7 times more comments, updates, likes etc. than the average Facebook user) and here is what Facebook is aiming for: Live audiences. Interesting for TV, because live audiences are their core business. FB emphasizes that during a soccer match in March, these people made >16 million actions on Facebook, most after goals were scored, and 89% of those came from mobile phones.
