Up until the invention of radio, communication had to be sent long distances along wires and cables. i.e. telegraph or telephone.
With the invention of radio, communication was not restricted to the use of wires.
Hence wireless is two words 'wire' and 'less' meaning without wire.

What were radios called in the 1940s?
They were called 'wireless', based on what would have seemed at that time to be their most astounding property: no wires. The miracle of communication over the 'wires' through telegraphy was just beginning to be thought of as commonplace.
Which satellite radio has the best reception?
All satellite radios will have equal reception as they meet a common wireless specification.
When were radios used in houses?
While the wireless or radio was invented in 1895, it was not used for entertainment until about 1920. The first radio station was started in Pittsburgh, PA in 1920 with commercial radios beginning sales about that time.
What were radios called in 1937?
By 1937, radio had long been known as "radio." But if you had been around in the early 1920s, radio was called a number of things-- wireless, wireless telephone, radiophone, and radio telephone. By the mid-1920s, however, the other words had fallen out of use, and radio was in fact only called "radio." What is interesting about 1937 is that FM was beginning to get into the news. In radio's first several decades, all stations were on AM. But in the late 1930s, inventor Edwin Howard Armstrong was demonstrating his new way of broadcasting-- which was generally referred to as "static-free radio"-- since AM signals tended to pick up all kinds of interference from the atmosphere, whereas FM signals did not.

What do you call the vacuum tubes used in transistor radios?
You don't, there aren't any. However some radios in the early 1950s did use both vacuum tubes and transistors. This was because early junction transistors were too slow to operate at RF so vacuum tubes were used in the RF and IF sections. These radios were called hybrid radios because they used both vacuum tubes and transistors.
How old are radios?
The first radios as we know them started production in 1909, but really did not take off until the 1920s when NBC created one of the first public stations. (and radio units became cheap enough to be in homes around the US and Briton) But the first radios were called "Wireless Telegraphy" and was invented in 1897.
