Hit Entertainment's chief executive officer Bruce Steinberg has resigned, with Jeffrey Dunn stepping into the role.
Dunn is the former chief operating officer for Nickelodeon Networks and the former president of Nickelodeon Film and Enterprises at MTV Networks.
During his 13-year spell at the company he was responsible for, among other things, taking Nickelodeon's network business around the world, for creating the Noggin joint venture with Sesame Workshop and building Nickelodeon Enterprises into the third largest licensing business in the world.
His appointment will give Hit an increased presence in its largest market, North America, and focus the organisation on further increasing the worldwide scale and imprint of Hit. Dunn will be based in the US, but will divide his time between the firm's New York and London offices.
"It is a privilege to be working with both Hit Entertainment and Apax," Dunn said. "The company owns some of the world's most iconic and successful brands and I look forward to helping take Hit Entertainment to the next level."
Steinberg commented: "I am proud to have been part of the team that has made Hit a tremendous success over the past few years."
