Amazon pulled its fourth-quarter advertising spend from Bloomberg, but the company's ads are still being served on the publisher's site.

According to a report from BuzzFeed News, Amazon pulled ads from Bloomberg on October 16 after the site published a controversial story alleging the Chinese government hacked Amazon and Apple's hardware by embedding microchips into third-party motherboards. A source familiar with the advertising relationship between the companies confirmed to Business Insider that Amazon stopped its "pretty significant" fourth-quarter ad spend.

But when Business Insider looked at Bloomberg's website on Friday, an ad for Amazon Prime promoting the upcoming show "Homecoming," starring Julia Roberts, appeared at the top of an article page from a story published on October 24 about Uber - purchased through programmatic technology.
