The sporting venue will become only the fourth cricket ground in the world to have hosted 100 Tests when England take on South Africa from 27 to 31 July.
PHA Media’s brief is to bring to life the cultural and sporting history of The Oval since its opening in 1845.
The agency will also tell the story of Surrey’s journey from near financial ruin into a business success story, as well as its development of the Kia Oval into one of the “finest modern venues in world cricket”.
The campaign will run for the next three months.
This is the second time that the agency has been engaged by Surrey County Cricket Club, following last year’s campaign to promote the NatWest T20 Blast to a family audience.
Tim Jotischky, senior consultant at PHA Media, added: “The Oval occupies a unique place in British sport as the venue for the first FA Cup Final, the first ever rugby international to be played in the England and as the birthplace of the Ashes, but what’s really striking is Surrey’s forward-looking approach and determination to ensure the Oval has a stellar future to match its glorious past.”
