Zenith Television Remote Control: A History of Innovation
The Zenith Television Remote Control has a rich history, spanning over six decades of innovation. From the first wired remote, the “Lazy Bones,” to today’s sophisticated infrared remotes, Zenith has been a pioneer in the field. This article explores the evolution of the Zenith television remote control, highlighting key milestones and the brilliant minds behind them.
From Wired to Wireless: The Lazy Bones and Flash-Matic
In 1950, Zenith introduced the world’s first television remote control, the “Lazy Bones.” This wired device allowed viewers to change channels and turn the TV on and off without leaving their seats. However, the connecting cable proved to be a tripping hazard, leading to customer complaints.
Zenith engineer Eugene J. Polley addressed this issue in 1955 with the invention of the Flash-Matic, the first wireless TV remote. Utilizing photo cells in the corners of the TV screen, the Flash-Matic responded to light signals from a handheld flashlight. While groundbreaking, the Flash-Matic had limitations, such as sensitivity to sunlight.
Overcoming Challenges: The Birth of Space Command
Zenith founder Eugene F. McDonald Jr., a staunch believer in commercial-free television, challenged his engineers to develop a more reliable wireless remote. Radio waves were considered but dismissed due to potential interference with neighboring televisions. Sound-based controls were also explored but deemed impractical.
Dr. Robert Adler, a Zenith engineer, proposed using ultrasonics – high-frequency sound beyond human hearing. This led to the development of the Space Command remote in 1956. The Space Command utilized aluminum rods that emitted distinct ultrasonic frequencies when struck, triggering corresponding actions on the TV.
The Ultrasonic Era and the Rise of Infrared
Despite its initial high cost due to the complex receiver technology required, the Space Command was a resounding success. It became the industry standard for over 25 years, with over 9 million ultrasonic remote control TVs sold. The advent of transistors in the 1960s allowed for smaller, battery-powered ultrasonic remotes.
By the early 1980s, infrared (IR) technology replaced ultrasonics. IR remotes use invisible light beams to communicate with the TV, offering greater reliability and functionality. Zenith’s advancements in cable-compatible tuning and teletext further enhanced the capabilities of IR remotes.
A Legacy of Innovation
Adler and Polley received numerous accolades for their pioneering work, including a joint Emmy Award in 1997 for the “Pioneering Development of Wireless Remote Controls for Consumer Television.” Their inventions revolutionized the way people interact with televisions and paved the way for the ubiquitous use of wireless remote controls in countless consumer electronics today. From the Lazy Bones to the modern Zenith television remote control, the company’s commitment to innovation continues to shape the landscape of home entertainment. The Zenith television remote control is a testament to the enduring power of ingenuity and the pursuit of a better viewing experience.
