Born in Dublin in 1938, Snow was brought up in Libya for part of his childhood, before becoming an ITN newscaster, then jumping to the BBC in 1980, where he has found fame ever since. He presented Newsnight for seventeen years, on which programme he used a sandpit to demonstrate troop movements in the First Gulf War. More recently, he presented 'Tomorrow's World'.
He is most fondly known for fronting the increasingly impressive (and silly) computer graphics used as part of the BBC's election night coverage, including Robert McKenzie's famous Swingometer. In 2005, he announced that he would be standing down from this role as he will be over 70 at the next election.
He has two famous relatives: the Channel 4 News anchorman, Jon Snow, is his cousin, and his son, Dan Snow, is an historian, who has regularly appeared on the BBC'S 'One Show' - and father and son have worked together on a history series for BBC2, re-enacting famous battles by means of computer graphics, among other things.
He survived a plane crash in Washington state, USA on 1st October 1999.
He once auditioned for the part of James Bond.
In a programme celebrating "Newsnight"'s 20th anniversary, Snow revealed that his worst moment on the programme was on an edition in 1984, when he interviewed Arthur Scargill regarding the notorious miners' strike. Scargill had produced a report on the subject and he vehemently referred to it to state his case. Snow tried to argue his own point, but was eventually forced to admit that he hadn't actually read the full report, therefore he couldn't ultimately make his point. Not that it affected him or his reputation much, if at all, but it was nevertheless a very uncomfortable and embarrassing experience for him.
His wife, Ann MacMillan, and her sister, the historian Margaret MacMillan, are both great-granddaughters of the former Prime Minister David Lloyd-George.
