MOUNTAIN VIEW, CA—Mark Cuban has barricaded himself inside the Computer History Museum, demanding recognition for inventing internet radio via Broadcast.com. The 66-year-old is holed up in the Internet History Gallery, living on vending machine snacks and energy drinks, until curators add his likeness to the “Pioneers of the Digital Age” exhibit. Staff say he blocked emergency exits with display cases and built a fortress from vintage Apple and IBM computers. “He keeps shouting that he ‘revolutionized audio streaming before anyone knew what streaming was,’” said security guard Janet Holbrook. Cuban, who sold Broadcast.com to Yahoo! for $5.7 billion in 1999, was incensed to find it mentioned only as a footnote. “I put live audio on the internet when people thought the Web was made by spiders. Where’s my plaque?” he told director Dr. Patricia Williams through the locked door. Curators slid documents noting pre-1995 streaming; he responded with chants of “No plaque, no peace.” Cuban is livestreaming the standoff as “Cuban Radio,” reaching confused janitors and a middle school tour that assumed it was an interactive exhibit. He’s also comparing himself to Marconi, which, sources say, is not an exhibit yet.
