A campaign has been launched to attract more American tourists to East Anglia by highlighting the region's links to the US military.
The initiative coincides with the 75th anniversary of the arrival of 180,000 American servicemen.
Ann Steward, project manager of The Friendly Invasion, said: "We're always looking for the economy to grow and very much the tourism opportunity here could be major.
"We're looking at real investment coming over we've put three tours together that we're launching today - a three day and a five day and a seven day.
"It's really just the start of something that we see as going to be much, much bigger."
The tours include some of the regions most recognisable landmarks such as King's College in Cambridge, Hylands House in Chelmsford and Sandringham Estate in Norfolk.
A new mini series on HBO called 'Masters of the Air' is also likely to boost tourism.
Kirk Saduski, a Hollywood producer, said: "It'll be the third part of our dramatising the American experience in World War Two.
"We did Band of Brothers which was about the 101st airborne, The Pacific which was about the marines in the pacific and now we're doing Masters of the Air which is about the eighth air force which was largely based here in East Anglia."
