Our History

Founded in an era dominated by the big buying shops, Nick Manning and Colin Gottlieb had a shared, clear ambition. They wanted to create a business where media would make a significant difference to their clients. So they wrote a ‘manifesto’ for the business, including the following words written 35 years ago, still relevant now:

“Given an ever-increasing choice, today’s media literate generation is developing a butterfly mentality in their media use…viewers, listeners..are swiftly moving targets and, as media specialists, we have to adopt an equally light-footed approach to media choice and tactics.

MGM had been created to put imagination back into media.

MGM was created to deliver what advertisers really need – imaginative media solutions allied to sharp negotiation. In other words, media that sells.”

In 1997, MGM became part of the Omnicom Group and in May 2002 MGM became Manning Gottlieb OMD, orbiting within one of the biggest marketing communications groups in the world.

The founding principles that Nick and Colin stood by all those years ago have remained at the heart of the agency and today Manning Gottlieb OMD is the largest agency within Omnicom Media Group, and the second largest in the UK with a headcount of 565+.
