1939 – Shockley Makes Historic Notebook Entry
William Shockley records in his
laboratory notebook that it should be possible to replace vacuum tubes with
semiconductors. Eight years later, he, Walter Brattain and John Bardeen at
AT&T Bell Laboratories successfully tested the point-contact transistor.
Shockley developed much of the theory behind transistor action, and soon
postulated the junction transistor, a much more reliable device. It took about
ten years after the 1947 discovery before transistors replaced vacuum tubes in
computer design as manufactures learned to make them reliable and a new
generation of engineers learned how to use them.
1949 – First UHF TV Station
Station KC2XAK of Bridgeport, Connecticut
becomes the first Ultra high frequency (UHF) television station to operate a
daily schedule.
Set up
as working experiment by RCA and NBC, the station was used to test if the UHF
spectrum was feasible to broadcast TV. Codenamed “Operation Bridgeport,” after
two-and-a-half years of successful transmission, the station was shut down. The
UHF transmitter was purchased, dismantled, and reassembled in Portland, Oregon
to power the first commercial UHF station in the United States.
2004 – Commodore Acquired
Once Commodore dropped from the
market in the 80’s, it pretty much stated bouncing around the world from
company to company. Ultimately it landed in the lap of KMOS – a Deleware
company. However, on this day, Dutch Manufacturer Tulip sells the company to
Yeahronimo Media Ventures for about US$32.7 million.
