what kind of technoligy did the United States have in the 1950"s?

Answer 1

Portable phones that tied up a radio channel per phone so only a thousand or so in Chicago. Television, black and white, in the early years only a couple of channels on only from 4 or 5 pm to midnight or so. Later, half hour long commercials for silverware or cookware. Jet transports were introduced very late in the decade, turboprop about halfway through. Automatic transmissions were becoming popular enough that driver's tests were dependent on the transmission. Seatbelts were not installed and cars were still sold without turnsignals in the early years. Getting in different cars meant discovering a different automatic transmission pattern as they differed. Radios had tubes and large batteries if portable. At the beginning there were no commercial computers, by the end there were a few dozen mainframes across the country and the first versions with transistors were just being planned. FORTRAN and LISP existed, BASIC and COBOL had not been developed yet.
