Pinterest sets its sights on Brazil: The company rolled out access to its ad platform in Brazil as it works to capitalize on a year of rapid growth and increased ecommerce across Latin America.

As the pandemic drove consumers to move their spending online in 2020, Amazon benefitted in a big way. But it wasn’t just its ecommerce business that grew by double digits. Its advertising business grew by 52.5% last year, pushing Amazon’s share of the US digital ad market past 10% for the first time. This has only strengthened its position as the No. 3 ad publisher in the US.

YouTube eases up on its ad rules: Though advertisers may not be happy about it, the platform’s move to relax its monetization policies is likely necessary to keep creators from jumping ship.

Elevated screen time is here to stay: Last year, US adults spent about 1 hour extra per day with digital media—and that boost will have lasting effects on consumption habits, even after the pandemic ends.
