Charting the evolution of public and political attitudes to homosexuality over the last four decades, from decriminalisation in 1967 to today's advances in gay sexual freedom, How Gay Sex Changed the World examines how the gay sexual revolution gathered pace in the face of gradually changing legislation, from the first Gay Pride march to groundbreaking dramas such as Queer as Folk.
