Jon Snow’s career in journalism began at LBC in 1973.

Thanking his viewers and bidding them an emotional farewell in his closing remarks, the 74-year-old journalist said it had “been the greatest privilege of my life to bring you the news”.

His final broadcast had been billed by Channel 4 as “the end of an era”, and a montage was played during the programme showing memorable moments from his career – as warm tributes poured in from viewers, media colleagues and politicians, including heads of government, past and present.

After the on-screen tributes closed with his former editor Ben de Pear describing him as “a giant of a journalist” but “a very humble man” and “a very beautiful one as well”, Snow concluded the programme by saying: “It's been wonderful and so rewarding after so long at the coalface of news.

“But in the end ... I am nothing in this studio without the significant and skilled technical and journalistic teams that, night after night, ensure that Channel 4 News comes to you. The joy of working here is those teams and their skills, technicians and journalists."

Among those to pay tribute to the veteran broadcaster was former Labour prime minister Gordon Brown, who said: “Jon Snow is a British institution and will always be so. Jon, your charitable work is less well known, but a tribute to your idealism.

“You deserve all our thanks for showing us that even amidst evil and injustice in this world a better world is possible.”

Scotland’s first minister Nicola Sturgeon said his absence would leave “a massive hole”, calling him “a top interviewer” but more importantly “just an all-round human being”.

Fellow broadcaster Piers Morgan described him as a “consistently brilliant news broadcaster, and aside from the ludicrous ties, and dodgy helmets, a lot of fun too.”

Snow has previously said he ignored instructions not to wear bright colours when he first started at Channel 4 and wanted to make “a bit of a splash” while on air, rather than appear “aggressively boring.”

The anchor donned a suitably colourful tie for his final broadcast, during which a montage showed some stories he covered over his time with the nightly news show, including the fall of the Berlin Wall, Barack Obama’s inauguration, and Nelson Mandela’s release from prison.

Over the footage, he could be heard saying in past comments: “I see myself as an informant. That’s my job – tell the truth, see where it takes us ... I never had an agenda but I had an attitude, and the attitude was that all that glitters is not gold.”

Snow’s career in journalism began at LBC in 1973. He moved to ITN three years later where he served as Washington correspondent and diplomatic editor, before becoming the main presenter of Channel 4 News in 1989, according to the Independent.

Channel 4 News has won 10 Bafta awards during his time there. Among the many awards won by Snow personally is the Bafta Fellowship – the organisation’s highest accolade. He has been named presenter of the year six times by the Royal Television Society.
