Douglas has been appointed to the newly-created role of director of programming and business development at Universal, starting on December 8.
She will focus on Globe Productions, a division launched by Universal Music in 2006 to create new television formats and TV platforms for its roster of artists, which includes Scissor Sisters, Take That, Amy Winehouse and Duffy.
As well as focusing on music properties, Globe's expanded remit under Douglas will include dramas and comedies across all media. Globe has produced online drama 'The Secret World of Sam King', shown on Bebo, and a BBC documentary about Paul Weller.
Douglas will also oversee Universal Music's UK business development strategy, including non-traditional artist rights, sponsorships and strategic marketing partnerships. The company's recent activity in this area created the pairing of Take That with Marks & Spencer.
Douglas resigned from Radio 2 at the end of last month taking ultimate responsibility for the broadcast of lewd messages left on 'Fawlty Towers' actor Andrew Sachs' answerphone by Russell Brand and Jonathan Ross.
She was at the BBC for 23 years taking over as controller of Radio 2 and 6 Music in 2003. Her role was expanded in May last year when she was appointed as the BBC's first controller of popular music.
David Joseph, chairman of Universal Music UK, said: "Our company and our artists have worked with Lesley for many years, over which time we have built huge respect and trust for her as a broadcaster and above all as someone who lives and breathes music.
"She has an exceptional rapport with artists and is simply one of the best media executives and leaders in the business."
Douglas said: "Over the past few years I have loved working closely with the music industry and the musicians within it. Being given the opportunity to work closely with the breadth of artists across Universal Music is a brilliant opportunity.
"It is an exciting, dynamic company and I am delighted to have been asked to join them."
