1935 Truetone (Western Auto) 3-band console radio.

Truetone was the private label radio, television and electronics
brand of Western Auto Supply Company of Kansas City, Missouri. Western Auto was a company founded in 1909 to sell tires and automobile supplies for the Model T Ford and other cars through
its catalogs and, starting in 1913, through retail stores in Kansas
City and other major cities. In 1915, Western Auto was split into
two companies, one in California and one in Kansas City.

In the late 1920s Western Auto was looking for new items to add to
its merchandise lines. After selling radio tubes under its "Wizard"
brand in the 1920s, the company offered its first Truetone brand
radios in 1931. Truetone was the radio brand sold by Western Auto
of Kansas City while the California company sold its radios under
the name "Western Air Patrol."

        The Hoffman “Easy Vision” television.

H. Leslie Hoffman (1906 – June 24, 1971) was an American businessman. He was the founder and CEO of Hoffman
Radio from 1941 to 1971, which changed its name to
Hoffman Radio and Television in 1948.

During the early years of television there was considerable
concerns that long term viewing television could damage
one’s eyesight due to eye strain. Hoffman took advantage
of this scare by advertising that the yellow-green tinted s
creen reduced eye strain. He marketed his televisions as
"Easy Vision."

The transistor radio was a technological marvel that put music
literally into consumers’ hands in the mid-1950s. It was cheap,
it was reliable and it was portable, but it could never even
approximate the sound quality of a record being played on
a home stereo. It was, however, the only technology available
to on-the-go music lovers until the Sony Corporation sparked
a revolution in personal electronics with the introduction of
the first personal stereo cassette player. A device as astonishing
on first encounter as the cellular phone or digital camera would
later be, the Sony Walkman went on sale for the very first time
on July 1, 1979.
