Online retail giant Amazon has been named as the most popular brand of 2013 in the US, while the BBC's iPlayer service topped the UK table.
The findings are based on YouGov's BrandIndex, which conducted over 3.5 million interviews over the course of the year, Econsultancy reports.
Consumers in both countries were asked: "If you've heard anything about the brand in the last two weeks through advertising, news or word of mouth, was it positive or negative?"
BBC iPlayer came ahead of John Lewis, despite the huge success of the department store's Christmas advert, which We Are Social claimed was the most talked-about campaign of the year on social media.
Korean electronics firm Samsung was third in the table for the UK.
Econsultancy said: "It's difficult to argue with the quality of BBC's streaming service, especially when comparing it to the competition from other broadcasters."
It also suggested quality content such as Doctor Who and Sherlock, as well as its easy-to-use interface, were responsible for its success.
In the US, Amazon displaced last year's number one, Ford, which dropped to second in the list. Third place was taken by sandwich chain Subway.
