Every winter, millions of people curl up on the couch and press play on the same beloved holiday movies -- whether it's Love Actually, The Holiday, The Family Stone or Four Christmases.
Snowy towns, familiar faces, predictable plot twists and happy endings aren't deal-breakers, they're the whole point.
This year alone, Hallmark Channel released 24 new holiday films, while streaming services like Netflix and Hulu rolled out their own. And despite the familiar storylines, viewers keep pressing play.
And, that's no accident, according to Virginia Tech experts.
