New York — The Home Depot kicked off its new national advertising campaign last night, with a 60-second branding spot airing during the "Grammy Awards" on CBS. Based on the theme, "The Home Depot is more than a store — You can do it. We can help," the new campaign is initially on TV with 30- and 60-second spots. It will eventually expand to include radio, print, collateral materials and the Internet. The company has said that it will increase its marketing support this year as it continues to invest in its business.
