The Grinch is back and he's meaner than ever! The Christmas classic remake landed at the box office on November 10th and was a big hit. Its debut earned $66million during the opening weekend. The movie owes its success to a snarky billboard campaign which went viral across social many media platforms. These ads were targeted at the citizens of such cities like New York and Los Angeles. They definitely couldn't turn away when they saw green billboards showing this grouchy character frowning at them and making mildly-offensive commentary. And despite being mean, these ads were completely on point and managed to reach a surprising target audience - millennials. According to Hollywood Reporter, 18 percent of ticket buyers on the opening night were between ages 18-24. Scroll to see the billboards below!
