London-based content distributor Digital Rights Group has found success for the reality format That’ll Teach ‘Em in Spain. Curso del 63, produced by Endemol-owned Zeppelin for Antena 3, is the most watched show on Tuesday evening primetime Spanish television. The success in Spain has led to talks between DRG and broadcasters in Italy, Greece, Chile, Brazil and Argentina. The reality format takes teens back in time, where they must live in the style of the previous era. The format is distributed under DRG’s Zeal Entertainment banner, and already has local productions for six international broadcasters to date, including M6 in France, Channel 4 in the UK and SBS in Belgium.
