Colgate is proposing a new marketing campaign called "Bright White" to promote their new whitening toothpaste. The 3 month $400,000 campaign will target English speaking Canadians aged 25-54. Key channels include out of home advertising for broad awareness, radio for frequency, digital for interactivity, and print in trusted publications. Research found competitors dominate search and social media, while Canadians spend significant time on mobile and watch TV daily, presenting channel opportunities. The strategy aims to move consumers through awareness to advocacy of the new formula.
