Airport Media was established last year by Tom Goddard, chairman of Ocean Outdoor and DigiCom OOH, to offer major UK airports a new, pure-play sales and management service.
LLA’s passenger count increased by 17% to 12.3 million in 2015, with four new airlines joining and 20 new routes opened across Europe, Africa, Asia and North America.
The airport is currently undergoing a significant transformation as a result of £110m investment by its owners.
The upgrade includes an expanded, modernised terminal building and improved access by rail and road.
The airport's commercial director, Rupert Lawrie, says: "We are delighted to join forces with Airport Media, who have demonstrated a fresh and innovative approach, with an in-depth understanding of the digital and OOH media space.
"They join us at an exciting time with the airport transformation programme taking shape.”
