The Radio 1 Breakfast Show

Nicholas Peter Andrew Grimshaw (born 14 August 1984) is an English television and radio presenter.
 He is best known for having hosted a variety of shows on BBC Radio 1 and has been host of "The Radio 1 Breakfast Show" since 2012.
 He is also known for his Channel 4 roles in T4 and "The Album Chart Show".
 In 2015, he was a judge on the twelfth series of "The X Factor".
Sarah Joanne Cyzer (née Cox; born 13 December 1974), more commonly known by her radio name Sara Cox, is an English broadcaster.
 She presented "The Radio 1 Breakfast Show" on BBC Radio 1 between 2000 and 2003.
 She currently hosts "Sounds of the 80s" on BBC Radio 2.
Dominic Anthony Byrne (born 10 November 1972) is a newsreader and presenter.
 He currently works on the Chris Moyles Breakfast show on Radio X, having previously worked as the newsreader for Capital FM on the Capital FM Breakfast Show.
 Prior to this he had worked with the BBC from 1997 to 2012, most notably as part of the on-air team on "The Chris Moyles Show" on BBC Radio 1 from 2004 to 2012, working as the newsreader and contributing to the show's zoo format.
 He also worked as a newsreader elsewhere on Radio 1, and presented on the BBC News Channel.
 He also runs his own voice training business called Open Mouth Productions.
 He returned to the new format of "The Chris Moyles Show" on Radio X in 2015, reading the news.
Marty in the Morning was RTÉ 2fm's breakfast show, presented by Marty Whelan, from 26 September 2005 until it was axed when Colm & Jim-Jim joined from FM104.
 The duo held the 2fm breakfast slot with "The Colm & Jim-Jim Breakfast Show" until the death of Gerry Ryan prompted a further change in the schedules in 2010.
 "Marty in the Morning" was an attempt by 2fm to find an able successor to Ryan Tubridy who had left "The Full Irish" and defected to RTÉ Radio 1 in 2005.
 However, in May 2006, it emerged that the show was receiving less listeners than its rival "The Ian Dempsey Breakfast Show" on Today FM.
 Prior to this, Whelan's predecessors Rick O'Shea and Ruth Scott had Tubridy's replacement "The Rick & Ruth Breakfast Show" axed after it emerged the flagship "The Gerry Ryan Show" was losing 40,000 listeners to Today FM's "The Ray D'Arcy Show".
 O'Shea and Scott were blamed for this and quickly disappeared off the morning airwaves.
 Whelan too disappeared and has not been heard on 2fm since.
Christopher James "Chris" Evans (born 1 April 1966) is an English presenter, businessman and producer for radio and television.
 He started his broadcasting career working for Piccadilly Radio, Manchester, as a teenager, before moving to London as a presenter for the BBC's Greater London Radio and then Channel 4 television, where "The Big Breakfast" made him a star.
 Soon he was able to dictate highly favourable terms, allowing him to broadcast on competing radio and TV stations.
 Slots like the Radio 1 Breakfast Show and "TFI Friday" provided a mix of celebrity interviews, music and comic games, delivered in an irreverent style that attracted high ratings, though often also generated significant numbers of complaints.
 By 2000 he was the UK's highest paid entertainer, according to the "Sunday Times" Rich List.
 In the tax year to April 2017, he was the BBC's highest paid presenter, earning between £2.2m and £2.25m.
Kevin Greening (30 December 1962 – 29 December 2007) was a British radio presenter, who co-hosted "The Radio 1 Breakfast Show" on BBC Radio 1 with Zoë Ball from 1997 to 1998.
David Lloyd Vitty (born 24 April 1974 in Hong Kong) is a radio presenter working in the UK.
 He worked alongside Chris Moyles at BBC Radio 1, having originally been a broadcast assistant on Moyles' early morning show.
 He became the show's head writer and 'Director of Comedy' and moved with Moyles to the drivetime slot, and then to "The Radio 1 Breakfast Show", during which time the programme was known as "The Chris Moyles Show".
 In total, he spent 14 years from 1998-2012 working alongside Moyles.
The Chris Moyles Show is the title given to two differing versions of a radio programme hosted by Chris Moyles, originally broadcast as The Radio 1 Breakfast Show from 5 January 2004 to 14 September 2012 before transferring almost three years later in September 2015 to the Global Radio-owned commercial radio station Radio X.
 The show is broadcast 6:30‐10:00am each weekday (originally broadcasting from 6:55‐10:00am between 2004-2007).
