Parker, who takes up his role this week, replaces Paul Amadi, who left to become director of funding at Diabetes UK. While Amadi was at the NSPCC, the charity led a series of marketing drives focusing on its ChildLine helpline service.
The appointment comes as the NSPCC gears up for an adult-focused campaign, encouraging people concerned about the safety or welfare of children to contact the charity.
Parker left C4 last year after a 20-year tenure there. He became the broadcaster’s head of strategic sales and commercial marketing in 2000.
The NSPCC spends about £4m a year on advertising. It recently moved away from campaigns based on ‘shock tactics’ to encourage consumers to engage with the brand.
