1940s   The first DJs emerge as entertainers for troops overseas. During WWII, persons armed with a turntable, a pile of records, and a basic amplifier would entertain troops in mess halls, spinning Glen Miller, the Andrews Sisters, and Benny Goodman.

The Talking Machine was hit hard by many historical and cultural developments. Radio became popular and movies expanded to dominate leisure time. The depression also hurt. The military had expanded with large vinyl disks. Eventually the music industry would become attracted to the concept of selling a whole album of songs on one record

The long-playing record or LP was invented in 1948 by Columbia Records. It played at 33-rpm and was 10 or 12 inches in diameter. The LP was made from flexible plastic vinyl (vinylite). These records used  microgrooves, and the  records recorded over 20 minutes of sound. In 1949, 7-inch 45-rpm records were introduced.

High fidelity became important in the  1950s. The LP was much more expensive than the 45-rpm disc or 10 inch disk but it became more popular. The hi-fi movement concentrated upon classical music recorded on LP. Movie soundtracks and Broadway show tunes were also important. If recording companies did not issue a 45 then the consumer would have to buy the more expensive LP at about 4 times the cost The Hi Fi movement utilized magnetic tape recording technology to refine the quality of performances which no longer had to be made "live" in the studio..

History of the Time

Events and trends
Technology

* First nuclear bomb

A nuclear weapon is a weapon that derives its energy from nuclear reactions and has enormous destructive power - a single nuclear weapon is capable of destroying a city. Nuclear weapons have been used only twice for war, by the United States against the Japanese cities of Hiroshima and Nagasaki during World War II. They have been used many hundreds of times, however, for the nuclear testing undertaken by many countries.

* First cruise missile

A cruise missile is a guided missile which uses a lifting wing and most often a jet propulsion system to allow sustained flight. Cruise missiles are, in essence, unmanned aircraft. They are generally designed to carry a large conventional or nuclear warhead many hundreds of miles with excellent accuracy. In 2001, modern cruise missiles normally travel at sub-sonic speeds, are self-navigating, and fly low in order to avoid radar detection.

Click the link for more information. and the first ballistic missile A ballistic missile is a missile, usually with no wings or fins, with a prescribed course that cannot be altered after the missile has burned its fuel, whereafter its course is governed by the laws of ballistics. In order to cover large distances ballistic missiles must be launched very high into the air and often to low earth orbit altitudes. Ballistic missiles are generally designed to deliver nuclear warheads because their payload is too limited for conventionally-armed ballistic missiles to be efficient, and because the extreme heat of re-entry would damage chemical or biological payloads.

The V-2 rocket was an early ballistic missile used by Germany during the later stages of World War II against mostly British and Belgian targets.

Pre-operational history

As early as 1927 members of the German Rocket Society had started experimenting with liquid-fueled rockets. By 1932 the Reichswehr started taking notice of their developments for potential long-range artillery use, and a team led by General Walter Dornberger was shown a test vehicle designed and flown by Wernher von Braun. Although the rocket was of limited ability, Dornberger saw Von Braun's genius and pushed for him to join the military.
