“After several years of experimenting, studios have thrown themselves deeply into a medium which is still barely understood. They are now developing elaborate social media campaigns early on, sometimes as soon as a film gets greenlit. Researchers are conducting deep numerical analysis on posts and tweets to guide marketing decisions, sometimes predicting box office revenue with pinpoint accuracy. They’re looking not just at opening movies, but sustaining their word-of-mouth through subsequent weeks. And they are getting more surgical about targeting their ever-fickle, ever-elusive core audience of young people.”
