For this first post I selected a one-page article from Popular Electronics, printed in August 1955.
Raytheon's new "Radarange" roasts a turkey in one hour, boils steaks in three and a half minutes, cooks corn and bakes potatoes in a few seconds - yep, that's the granddaddy of the ubiquitous microwave oven.
Let's have a look at a page from Popular Science, October 1955:
Lovely transistor-based radios - and a lady enjoying some nice Jazz or bluegrass with her very portable radio. She could take it with her on a bicycle trip without even noticing the weight.
A battery-powered phonograph (turn-table player) - perfect for outdoors parties, not so great for jogging with it.
In 1955 the transistor, the first solid-state device capable of amplifying an electric signal, was not anymore a breakthrough technology, though the vacuum tube was still king in the marketplace. In the "Transistors Take Over Portables" column, the author actually mean electron tube-based portables - there were battery-powered portable radios that used vacuum tubes that were somewhat sparing in their power consumption.
