The First Transistor
John Bardeen and Walter Brattain at Bell Laboratories constructed the first solid-state transistor. This PNP point-contact germanium transistor operated with a power gain of 18 on Dec. 23, 1947. With their manager, William Shockley, they won the Nobel Prize in 1956.

The First Transistor Product
The first transistor radio was a joint The first transistor radio was a joint project of the Regency Co. and Texas project of the Regency Co. and Texas Instruments. TI built the transistors; Instruments. TI built the transistors; Regency built the radio. On October Regency built the radio. On October 18, 1954, the Regency TR1 was put 18, 1954, the Regency TR1 was put on the market. It was a scant five on the market. It was a scant five inches high and used four germanium inches high and used four germanium transistors.transistors. It was discontinued in 1955.

The First Transistor Product
When Regency quit producing their radio, the Japanese company immediately started shipping their radio to the U.S. One immediate problem was that Americans couldn’t pronounce their name. The founders, Ibuka and Morita, thought of using a Latin word sonus meaning "sound." Akio Morita knew some English, and made a simple variation that became their name from then on: SONY
Sony
In Japan, a tiny company had other ideas. Tsushin Kogyo was close to manufacturing its first radios when it heard that an American company had beaten them to market. But they persevered and made a radio, the TR-52.

Further Scaling will be possible if…..
• The key is in:– Extending existing CMOS technology
• or – Devising new nanotechnology – New methods of computing– New architectures
