1926 demonstration of sound.

Sound Motion Pictures.

  Who can forget the film "Woodstock"? Or Pink Floyd's "Live at Pompeii"? You have? Well, despite the fleeting nature of rockumentaries, the technology that made them possible was pioneered by AT&T. It was called "Vitaphone" and it recorded music and sound effects on large, high fidelity discs that were then synchronized with the on-screen action. "Don Juan" was the first Hollywood feature film with a Vitaphone soundtrack.
