This is a timeline of Capital London, previously known as Capital Radio, 95.8 Capital FM or similar variations, from its initial period as an Independent Local Radio station for Greater London to the present day CHR network serving most of the UK.

• 1970
  • Capital Radio is formed in early 1970 by Nicholas Vincent-Brown, David Maule-ffinch and one other friend Tony Parmiter with the intent to apply for London's Independent Local Radio general entertainment licence. In late 1970, future brothers-in-law Vincent-Brown and Maule-ffinch's father-in-law, Barclay Barclay-White, become involved. By the time the consortium applies to the IBA, Capital Radio's board also includes Richard Attenborough, George Martin, Bryan Forbes and Peter Saunders (impresario).^[1]
