Olympic athlete Roger Black is to front a £2m dry petfood marketing programme for Purina O.N.E brand. The TV campaign for the premium cat and dog food is designed to raise awareness and promote trial. The 30 second adverts which will run on terrestrial and satellite TV show Black returning home from a run with his labrador to feed it a bowl of Purina O.N.E. Black, who is just back from the Sydney Olympics, was chosen to represent the brand which launched in July as he is associated with optimum fitness. The TV campaign will be reinforced with a press campaign in women's and pets interests magazines, featuring money off coupons. {{P&P }}
