• Big screens continue to dominate viewership globally, commanding over 50% of share in every region except Asia. Notably, Asia was a bright spot for big screens, as their share is growing rapidly in the region. • Connected TVs’ share of viewing time fell for the first time ever, and of connected TV-first device manufacturers, only Roku grew, while Apple TV and Amazon Fire TV dropped 1% and 7%, respectively. • Globally, video quality improved, with one big exception—start time. Video start time was up to over five seconds, while ad start time also rose substantially to 2.6 seconds as technical issues left viewers waiting for both content and ads in Q4. • YouTube Shorts seem to be gaining traction, as shorter-form content grew more than 2% from last year on the platform best known for long-form videos. • U.S. sports leagues saw their high mark in engagement on social media in Q4, besting pre-pandemic numbers captured at the beginning of 2020.
