The company said almost one in four visitors to its dedicated Winter Olympics microsite downloaded a tailor made podcast featuring a guide to the host city Turin.
The hour-long guided tour to the Italian city also included a list of restaurants and shops in which Amex customers could snap up bargains or obtain member discounts.
Amex said the success of the Turin podcast could lead to similar projects to link customers with shops, restaurants and other facilities.
Marketing director Ellen Goodman said: “The American Express Travelcast is an innovative way to help tourists go beyond sightseeing, and the results reflect the growing passion for podcasts among our customers.
“Using the Travelcast to link our Cardmembers with merchants who are providing unique and valuable offers is a win for merchants and for our Cardmembers, and we will continue to look for opportunities to use this technology in the future.”
The microsite also allowed users to download a PDF map of Turin.
