For the first time ever, the U.S. is launching a marketing campaign to try and draw tourists from around the world.

Starting May 1st, the "Discover this land like never before" ad campaign will target three intital countries-the UK, Candada, and Japan.

Brand USA...a joint public-private partnership, is behind the campaign and will use print, tv, and internet ads. It will also use billboards and social media to highlight America's national parks, diverse cities, and world class citizens.

A second media blitz will target Brazil and South Korea...with more countires to follow.

Organizers say the campaign is needed to remind the world's tourists the U.S. is a top travel destination.
