Research found that the Colorado Tourism Office‘s $4.5 million “Come To Life” television ad campaign, which ran in target markets last April, May and August, stirred $898 million in spending in the state. That doubles the return on investment from previous ad campaigns.

“Any campaign is a combination of ad creative and in-market execution, and the combination really paid off big time for us,” said Al White, director of the state’s tourism office. “It was really dramatic to see what happened.”
