22 October 2025 In this week's Mumbrellacast, Hal Crawford, Tim Burrowes, Nathan Jolly and Abe Udy discuss Mumbrella's widespread changes as part of a larger project to bring Mumbrella and Unmade content together on the one platform. We also look at Seven West Media's upfront event in Sydney, which features the launch of a partnership with Westpac to link 7plus advertising and real-world sales, and 7 Geo Plus for location-based targeting. Seven's chief content officer Brook Hall tells Mumbrella there's a new spirit of collaboration between broadcasters, and the hosts unpack what audiences and marketers can expect from the company over the next 12 months. Meanwhile, OpenAI released a new web browser overnight -- ChatGPT Atlas. AI-powered browsers have been around for several months -- Perplexity's Comet was launched in July -- but the launch of Atlas is a big deal for the tech landscape. For a deeper dive into OpenAI's browser see Tim's analysis on our website.
