DJ Chris Moyles, who has announced he is leaving the Radio 1 Breakfast Show, is the show's longest-serving presenter after making his debut on 5 January 2004 (pictured here). More than 7 million people every week tune in to his show, once described by its host as "three hours in which I can be as brutally honest as I want". His mother Vera is now a fixture at music festivals.
Tony Blackburn was the first DJ to helm the early morning show. He played the first record on Radio 1 - Flowers in the Rain by The Move - at 07:00 on 30 September, 1967. Blackburn says he chose the song "because it was a hit at the time, it had a crashing noise and it was a nice lively record".
Noel Edmonds took over in 1973, bringing an anarchic sense of humour to breakfast time. He played elaborate pranks on his listeners and once pretended to present an entire show on a passenger jet flying from London to Glasgow.
Dave Lee Travis shepherded the show through the punk era, helming the nation's most listened-to breakfast broadcast from 1978 to 1980. He remained with Radio 1 until 1993, when he dramatically resigned on air.
Mike Read - pictured here (second left) with the sartorially challenged Radio 1 Roadshow team - was in charge from 1981 to 1986. Read could often be heard strumming his guitar on air and notoriously banned Frankie Goes To Hollywood's single Relax, helping it on its way to number one.
Mike "Smitty" Smith joined Radio 1 from Capital Radio in 1981. He graduated to the Breakfast Show in May 1986 and lasted for two years, during which time Diana, Princess of Wales, declared he was her favourite DJ. His tenure coincided with the rise of Stock, Aitken and Waterman, of whom he was not a fan. "Their songs weren’t great," he said. "I love great pop music but we were machine-gunned with this stuff."
Simon Mayo ushered in the 1990s with a fast-paced, zoo-style breakfast show, which also made stars of weather girl Sybil Ruscoe and newsreader Rod McKenzie (now in charge of Newsbeat). Mayo - pictured here with The Pogues' singer Shane McGowan (right) - introduced the famous Confessions feature, where listeners would own up to nefarious misdeeds.
After five years, Mayo gave up early starts for a mid-morning slot. Radio 1 tried both Mark "Goody Bags" Goodier (left) and Steve Wright (right) as replacements but neither lasted long. Their stints coincided with the cull of some of the station's longest-serving presenters, including DLT and Simon Bates, which saw the station lose five million listeners in seven months.
Chris Evans' breakfast show gave Radio 1 a huge boost, and constant headaches. Every show generated a tabloid headline - especially when he stopped turning up - but listeners often got to work late themselves as they lingered over the radio to hear the ongoing soap opera. Evans' memorable features included Honk Your Horn and Ginger Loans, in which listeners had to write in to beg for a cash loan of "up to one pound".
When Evans quit in January 1997, station controller Matthew Bannister paid for an electronic billboard in Piccadilly Circus that read: "New Radio 1 DJ wanted, ginger hair an asset." In the end the show went to cult afternoon duo Mark and Lard (Mark Radcliffe and Marc Riley). The duo, who broadcast from Manchester, said they felt alienated from the station's bosses in London and were quietly dropped after just eight months. Both presenters now broadcast for BBC 6 Music.
Zoe Ball and Kevin Greening were drafted in as Mark and Lard's replacements, Greening having subbed for the duo in the days following the death of Diana, Princess of Wales. Greening was a trusted radio voice who could run the technical side of the show, while Ball brought stories of her party girl lifestyle. On their first show, she told listeners she was wearing a feather bra and they could "see her knickers if they wanted". She later took sole control of the show.
When Ball announced she was leaving to start a family with her husband, DJ Norman Cook, her best friend Sara Cox stepped in to take her place. She celebrated the news with a glass of champagne outside Radio 1's headquarters and soon found herself knee-deep in mud, broadcasting from the Glastonbury Festival.
The Breakfast Show came full circle in 2007, when Chris Moyles and Tony Blackburn co-hosted the show to celebrate Radio 1's 40th anniversary. Moyles, the self-styled "saviour of Radio 1", waited until he had beaten Blackburn's record as the longest-serving breakfast show host before announcing his decision to step down this week. "We're off," Moyles told listeners. "A couple more months of us, then it's someone else's turn."
Youth presenter Nick Grimshaw will step into Moyles's shoes in September. The 27-year-old, who joined Radio 1 in 2008, said: "It's been a dream of mine since the age of 11 and to be honest it hasn't really sunk in yet."
