Short-Form Video is Getting Bigger on YouTube
Short-form videos (less than one minute) made up 77 percent of total views on YouTube last year, according to data from Tubular Labs, as reported by TVREV, continuing the rise of Shorts on the Google-owned platform. The research found that the increase coincides with a decline in long-form videos’ (20+ minutes) share of global views on YouTube, with long videos falling from 6.98 percent of all views in 2023 to 4.08 percent in 2025.
UK Publisher Revenues Grow Despite Half Reporting Declines
UK digital publishers’ revenues were up 4.24 percent over the same quarter last year in Q3 2025, according to the Digital Publishers’ Revenue Index (DPRI) from the Association of Online Publishers (AOP) and Deloitte, marking the third consecutive quarter of YoY growth. But the report noted that 50 percent of participants reported declines, suggesting that “overall growth trends are being carried by a load-bearing few.”
Majority of US Households Use Smart TV as Primary Video Streaming Device
Sixty-one percent of US households now use their smart TV as their primary video streaming device, according to research from Parks Associates, up from 39 percent in 2021. Streaming devices (such as the Amazon Fire Stick and Roku Streaming Stick) have maintained their 30 percent share over the same period, while the use of games consoles and other connected devices (such as smart Blu-ray players) for video streaming has fallen below 10 percent.
Tech and Data Constraints Pose Barriers to Martech and Ad Tech Integration
Advances in AI are helping marketers integrate their martech and ad tech stacks, according to a new survey from EMARKETER and Zeta Global, with 78 percent of respondents expecting full convergence within three years. But the survey identified ongoing barriers to integrating these systems, with technology constraints (such as latency and incompatibility) cited as the primary hurdle, followed by data incompatibility and the persistence of organisational silos.
