Forrester will join Primesight in late June, replacing sales director Nigel Clarkson who, as Media Week announced in February, is leaving the company to join daily deals site LivingSocial at the end of April.
In his new role, Forrester will be responsible for the sales and marketing functions at Primesight and will lead a team of 70.
He will report into Naren Patel, chief executive of Primesight, who said Forrester's previous experience at large companies such as CBS Outdoor, The Mirror Group and The Guardian, along with his role at Amscreen, provided a "unique breadth of knowledge and experience, which we feel is a natural fit for Primesight."
