Megaphone TV and Flash Player End of Life: December 31, 2020

Adobe Flash Player has officially been discontinued, and will stop functioning in Chrome, Safari, Firefox, IE, and Edge on December 31, 2020. Although Megaphone TV’s “on air” graphics application currently requires Flash Player, Megaphone is actively developing a new on-air application that will no longer require Flash Player. When the new on-air application is ready, Megaphone TV will contact all customers to provide a smooth transition away from Flash Player.
