AGUSTA, MAINE (AP) -- Maine officials say revenue from the state's tourism industry has increased for the fourth straight year in 2016. A report from the Maine Office of Tourism shows that revenue grew to just under $6 billion last year, an increase of about 6 percent from the previous year. Officials said Wednesday the total economic impact of tourism reached $9 billion. Data shows that visitation has risen to almost 30 percent from the 28 million visitors in 2012. Spending grew by about $1 billion over the same period. Visitors spent the most on retail sales, lodging, restaurants and food. The agency is launching a new marketing campaign this year called "This is Me" in an effort to continue growth. Officials say the campaign aims to frame the state as a lifestyle brand.
