On May 3rd, Hollywood film and TV writers went on strike after the Writers Guild of America and the Alliance of Motion Picture and Television Producers failed to reach a new contract agreement. The strike was prompted by streaming platforms shortening TV seasons and hiring fewer writers for briefer stints, and the shift to new models of consumption (like streaming).
