Jumbotron
（重定向自Video Board）
A Jumbotron, sometimes referred to as Jumbovision, is a large-screen television using technology developed by Sony, typically used in sports stadiums and concert venues to show close up shots of the event. Although JumboTron is a registered trademark owned by the Sony Corporation, Sony stopped manufacturing the devices under that name in 2001 and the word jumbotron has since become a genericized trademark.
