Second-screen usage is the latest way consumers engage with television content. According to the latest Nielsen data, 75 percent of smartphone and tablet users are engaging with second screen content more than once a month as they watch TV. And about half of those people are engaged with second screen content daily—that’s about 50 million people. This is good news for brands and advertisers, according to Nielsen’s Eric Ferguson, VP Media Client Services, because the additional exposure across screens is having a big impact on ad effectiveness.
