TV Shows Carry Significantly Higher Ad Loads Than Movies on US Streaming Services 

TV shows on US streaming services carry approximately double the ad load of movies, according to research from Ampere Analysis. The difference is particularly stark on Paramount+, whose ad load on movies is 10 times lower than its TV shows. “Films rely on maintaining narrative and cinematic immersion, so ad breaks are typically less frequent to align with the viewing experience,” said Callum Sillars, Senior Research Manager at Ampere. “By contrast, TV series naturally lend themselves to more ad opportunities, as episodic content has organic breakpoints both during and between episodes, enabling higher ad loads.”

Magazine and Newspaper Ads Offer Highest ROI for UK Retail Brands, Finds IMS

Magazine and newspaper advertising offers 9.6x ROI for UK retail brands, according to econometrics agency Independent Marketing Sciences (IMS), based on data analysed from over 270 IMS campaigns over the last decade. The research found that radio (6x) and TV (5.9x) advertising outperformed certain digital channels, such as paid social (5.7x), shopping PPC (5.1x) and SEO (1.6x). “Many retail brands – and, in particular, the venture capitalists and private equity funds that own these brands – instinctively flock to digital, and accept the ROI data that digital platforms promise as gospel,” said Alex Vass, Founder and CEO of IMS. “But very often, digital platforms overclaim their impact on sales and omit to mention the role of other marketing platforms in driving conversions.”

CTV Consumption Growth Outpaces Mobile Video in US Forecast 

The average time US consumers spend watching CTV video is projected to reach two hours and 47 minutes per day in 2027, according to forecasts from EMARKETER, compared with 1 hour and 39 minutes for mobile video. The data projects average daily time spent watching CTV to grow by 24 percent between 2023 and 2027, versus 13 percent for mobile device video.
