Online shopping based Seattle firm, Amazon Inc. revealed it’s experimenting adverts with personalized video.
The clips feature images and text about products the US retailer has detected the user has shown interest in.
Amazon regularly displays customized static ads on third-party sites, but the videos have the potential to be more eye-catching and appear in more places.
One expert said the idea had potential but Amazon would have to be careful that its ads did not seem creepy.
“This is something we’ve only experimented with at very small scales,” Graeme Smith, managing director Amazon’s software development center in Edinburgh, told the BBC.
“They have been out there in the wild.
“I’m not able to share any more details of where, but potentially anywhere you can see a video is potentially somewhere you could consider running personalized video ads, right across the internet.
“It’s still very early days for this technology, but it’s something we are really excited about with a lot of applications.”
Mr Smith showed off one of the ad designs at a press conference in London.
But the company declined the BBC’s request to show the footage, saying it was still in a testing phase, so too early to share widely.
