The Manchester-based firm was run by Mike Farnan, the former managing director of Manchester United International.
Said Peter Harrison, chief executive of Global Marketing: "The acquisition of Global Brand Strategy complements the offerings of Global to its worldwide client base.
“Mike Farnan joins a powerful management team of marketing professionals that is quickly forging a high reputation for delivery in world sport following the successful purchase earlier this year of the Jardine public relations business."
Global Marketing, best known for its motorsports work, is a privately-owned agency providing sponsorship, event management, public relations and licensing services to clients worldwide through offices in London, Atlanta, Sydney, Melbourne, Cologne, Zurich and Manchester.
Jardine Communications was purchased by Global Marketing Communications in February 2003.
