YouTube Runs Two Live Attention Experiments
Google ran two simultaneous experiments that alter how live attention is monetized on its video properties. On YouTube TV, Neal Mohan announced a fully customizable multiview where Google composes four live channels server-side — giving Google compositional control and ad decisioning. Separately, YouTube tested side-by-side livestream ads that keep the video visible but mute the livestream audio until the ad ends, making audio the proxy for attention. The two architectures create different attention signals for buyers: compositional control on YouTube TV and audio-dominant attention on YouTube livestreams. The experiments raise measurement and media-buying challenges for advertisers who cannot reliably know which screen or sensory channel delivered attention.
A major platform (Google/YouTube) is testing distinct live-ad monetization architectures that change what counts as 'attention' for buyers; this affects measurement, ad buying and attribution across streaming inventory.

US Government Excludes Microsoft from Visa Program
The US government has barred Microsoft from participating in the permanent residency process for foreign workers with H-1B visas, accusing the company of abusing the program. Vice President JD Vance stated that Microsoft laid off 6,000 American employees last year while benefiting from 6,300 H-1B visa holders. The Department of Labor, led by Keith Sonderling, will not accept new permanent residency applications from Microsoft, as well as several consulting firms and Adobe. This action comes weeks before the midterm elections and reflects the Trump administration's broader criticism of the H-1B program, which it claims disadvantages American workers. Microsoft has not yet responded. The move could impact the tech industry's ability to retain skilled foreign talent.
