As a media façade, the ABC Times Square Studios’ LED display is a sight to behold. Nine, curvilinear, horizontal, LED video ribbons undulate around the facade’s front. Home to ABC’s Good Morning America, the building presents what seems to be a gigantic TV screen that displays network news and upcoming program and entertainment previews. Actually, the display, the only LED sign in the world that’s integrally involved with a major-TV-network program, is trailblazing the future of mediafaçade-based “performance signage.”
