The history of these televised contests can be, in part, traced back to holiday camps, according to Annette Hill, professor of media and communication at Lund University, Sweden: "The best talent shows are great entertainment, full of warmth and empathy," she says. "If you look back at Butlins in the UK in the 1930s and 1940s, it was mainly a working-class holiday camp that offered a whole entertainment experience and at the heart of it were the people known as the Red Coats, who had to provide a warmth of atmosphere."
