To mark its 40th anniversary The World Tonight has been going through the archives for key moments.
On Monday April 5th, we produced a special edition of the programme. We looked back at the stories we covered in the first days of The World Tonight and examined how those stories have moved on - these included Northern Ireland, the rise and fall of the Khmer Rouge in Cambodia, as well as an interview with the first presenter of the programme, Douglas Stuart.
Listen again to The World Tonight 40th anniversary edition (5th April 2010).
