The agency's work for Callaway under Mark was particularly groundbreaking, helping to bring a hip vibe to golf advertising that is now the norm. In one memorable Callaway campaign, wide-eyed golfers explain their theories about why the balls go so far. One addled duffer claims it's because Callaway balls are made from rocks brought back from the Apollo moon landing. "We're really proud of what we've done," says agency president Jim Matthews.
Mark, reached at his San Diego home, says he left the agency to pursue a "soon to be announced" project. "I wish them the best," he says. "I was glad to lead a great team." Matthews says a search for Mark's replacement is "well underway."
