Tonight (often referred to as The Tonight Programme) is a British current affairs programme, produced by ITV Studios (formerly Granada Television) and ITN  for the ITV network, replacing the long-running investigative series World in Action in 1999. Previously airing twice-weekly, on Monday and Friday evenings at 8.00pm (ITV Wales, STV and UTV would often air the show at different times or different days, to make way for regional programming), the show runs the gamut from human interest-led current affairs to investigative journalism. Tonight has conducted interviews with a plethora of political and public figures, including George W. Bush, Tony Blair and Hillary Clinton. From 1999-2007, the programme was known as Tonight with Trevor McDonald.
