Duke Marketing, which has spread the image of the Isle of Man worldwide with its motorsport DVDs and videos, has agreed a partnership with ESPN, the international television broadcaster.
It means the company will create and operate a bespoke online shop integrated into ESPN's website.
The merchandise will include books and clothing.
It's anticipated it will bring in business to the Island and help promote the TT.
ESPN has shown year on year growth since its arrival on the scene six years ago.
ESPN Classic is on Sky channel 442 in the United Kingdom.
