YouTube Tests Thumbnail A/B/C Testing
YouTube announced a Test and Compare feature enabling creators to test up to three thumbnails (A/B/C) for long-form videos in YouTube Studio. The test measures Watchtime to identify the best performing thumbnail, with results visible in the test report. Tests may run for hours to weeks depending on thumbnail similarity, and the platform will display the best-performing thumbnail at the end; if no clear winner exists, the initially selected thumbnail remains. Creators can also change thumbnails manually during or after testing. Thumbnails must comply with Community Guidelines and are not available for children-focused videos or Live streams. The announcement came via Threads from YouTube CEO Neal Mohan, and the piece offers thumbnail design tips (high contrast, central focus, minimal text). The article also notes related experiments (Google Lens search inside videos, context notes like Community Notes) and cites an 8,000-video ad analysis using Google AI.

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.
