Hardtalk (styled as HARDtalk) is a BBC television and radio programme, consisting of in-depth 25-minute one-on-one interviews. It is broadcast four days a week (Monday to Thursday) on BBC World News and the BBC News channel. Launched in 1997, much of its worldwide fame is due to its global reach via BBC World. Until early 2005, the host was Tim Sebastian, whose famous, and sometimes controversial, style of tough questioning brought a huge world audience to the show. It is normally broadcast late at night on the BBC News Channel. Until the mid-2000s, it was broadcast at around 11:30 pm, but in more recent times it has been broadcast an hour later at 12:30 am. In 2015 it was moved to an earlier slot 20:30 in the evening as part of a changes to the channel.
