Social Media and Influencers Are Least Trusted Media for Business Leaders
Newspapers and news brands are the most trusted forms of media among business leaders, according to new research from the IPA and the Financial Times, with radio and TV channels also seeing high levels of trust.

Women’s Sport UK Reach Falls for First Time in Three Years
During the first five months of the year, broadcasting reach for women’s sport in the UK fell for the first time since 2022, according to the Women’s Sport Trust (WST) Visibility Report. The WST noted that the decline coincided with a 15 percent reduction in coverage hours, but that there were still “standout moments” so far in 2025.
“The Women’s Boat Race was the UK’s most-watched women’s sporting event of 2025 so far, peaking at 2.18 million viewers,” said the report. “Football and rugby filled the rest of the top 10, with the Lionesses and home nation rugby teams featuring heavily – highlighting all their continued appeal to the viewing public.”
Open Web Spend Has “Barely Grown” as Walled Gardens Capture Ad Dollars
Digital ad spend in walled gardens has more than doubled since 2020, according to figures from WARC and Jounce Media, while open web spending has risen only 41 percent over the same period. WARC’s Future of Programmatic 2025 report observes that while programmatic advertising is set to grow double-digits this year, “this masks the fact that open internet spending has barely grown over the last few years, with almost all of non-search digital advertising growth going to the walled garden platforms.”
