Ad tech giant Taboola has struck a deal with Apple to power native advertising within the Apple News and Apple Stocks apps in Canada, the U.S., the U.K. and Australia.

As part of the deal, Taboola becomes an authorized reseller of ads on Apples News and Apple Stocks. The company will be able to sell ads to advertisers within the app’s main feeds, as well as in articles from select publishers.

While Apple does not disclose how many people use its apps, last year it said it sold more than one billion subscriptions to its paid platforms, which includes News and Stocks apps.

This is not the first time the company has worked with a third party on ad sales. Prior to working with Taboola, Apple had a deal with NBCUniversal to sell ads for the same apps.

Taboola partnered with Apple after closing a deal with Postmedia to create monetization opportunities and drive user engagement on news sites. Under that deal, Postmedia integrated Taboola Feed – which provides multi-format content recommendations for readers – into its outlets, including the National Post, Financial Post, Vancouver Sun and Toronto Sun. Prior to that, Taboola partnered with Yahoo Canada to enable its clients to place native ads on the company’s digital properties.

Tabools is a New York-based company that works with more than 9,000 publishing partners to sell native ad space on their properties to more than 18,000 advertisers worldwide. According to the company, more than 15,000 advertisers use its products.
