Yes they were there to give information
This is so because back in the 1940s thetelevision channels used up to 600 times the frequency of radios so they set off channel 1 (45-50) for people with mobile radios.
telivision was invented in the 1940s. In the 1970's radios were invented and mostly sports were still famous
well i know that FM was invented in the 1930s so i gess they had mostly audio programs and live baseball games from what i know
The radios of the 40s were pretty good and could pull in stations from long distances. The sound on the other hand was mono and was not that good. They were also not very dependable as they contained vacuum tubes instead of transistors, which only lasted so long and needed replacing from time to time.
During 1940's there use to be radios for watching, and alson in the 1950's. In the 1940's people used radios without screens, not cable TV. In the 1940's the radios had speakers, and no screen. In the 1960's people had black and white TV, not color TV. In the 1990's people finally had color TV, but it's not HD.
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.

How many radios were purchased when?
The Bose corporation makes bose radios for your enjoyment. No other company makes the bose radios or any radios quite to their standard.
Regular household AM radios pick up stations on frequencies between 550 KHz to 1.7 MHz . . . wavelengths between 176 meters and 545 meters. Regular FM radios pick up stations on frequencies between 88 MHz and 108 MHz . . . wavelengths between 2.8 meters and 3.4 meters. 'Short wave' radios, taxi radios, police radios, CB radios, firetruck radios, aircraft radios, weather radios, satellite radios, toy walkie-talkie radios, cellphone radios, computer WiFi radios, cordless telephone radios, garage door opener radios, Bluetooth radios, 4G iPad radios, and microwave oven radio transmitters all have their own separate frequencies/wavelengths that they operate on, so that they don't all interfere with each other.
Oh, dude, it's "radios'." Like, you just add an apostrophe after the "s" when you want to show that multiple radios own something. So, if you're talking about the antennas on a bunch of radios, you'd say, "The radios' antennas are all tangled up." Easy peasy.
