==History==
In the early 1960s, airline headsets were so large and cumbersome that many pilots had switched back to the use of handheld microphones for communications. The speed and complexity of jet airliners caused a need for the introduction of small, lightweight headsets into the cockpit. In 1961, United Airlines solicited new designs from anyone who was interested. Courtney Graham, a United Airlines pilot, was one of the many who thought the heavy headsets should be replaced by something lighter. He collaborated with his pilot friend Keith Larkin to create a small, functional design which was robust enough to pass airlines standards. (Larkin had been working for a small company called Plane-Aids, a Japanese import company which offered spectacles and sunglasses that contained transistor radios in their temple pieces.)〔(【引用サイトリンク】title=NASA Spinoff 2005 )〕 The final design, incorporating two small hearing aid-style transducers attached to a headband was submitted to United Airline approval. UAL's approval of the innovative design caused Graham and Larkin to incorporate as Pacific Plantronics (now called Plantronics, Inc.) on May 18, 1961. They introduced the first lightweight communications headset, the MS-50, to the commercial marketplace in 1962.
In the mid-1960s, the Federal Aviation Agency selected Plantronics as the sole supplier of headsets for air traffic controllers, and thereafter was selected to supply headsets to the operators of the Bell Telephone company.
