“Sometimes we stare so long at a door that is closing that we see too late the one that is open.” — Alexander Graham Bell
Bell Labs, the industrial research and scientific development arm of the American Telephone and Telegraph Company, announced to the world 72 years ago today that the company’s engineers had successfully invented a transistor radio — one of the most important inventions of the twentieth century. American scientist Alexander Graham Bell revolutionized telecommunications after being granted the first patent in the United States for a telephone in 1876 — and less than a decade later, Bell co-founded the American Telephone and Telegraph Company — better known as AT&T. After more than a century since its creation, AT&T has evolved with the industry and is now the world's largest media and entertainment company in terms of revenue. For their participation in the development of the transistor radio, physicists and Bell Labs engineers John Bardeen, Walter Brattain and William Shockley were awarded the 1956 Nobel Prize in Physics.
