With more advanced technologies, radios became smaller and more affordable which led to the popularization of radio broadcasts in many countries worldwide through broadcast networks that continued expanding into separate regional stations or local broadcasting with multiple transmitters covering larger areas on different frequencies. These older technologies used simple wire antennas instead of modern broadcast band frequencies and had very limited range due to lack of amplification and sensitivity compared with later models introduced after World War I using vacuum tube technology. The earliest type of radios didn’t even require electricity such as crystal sets or other early wireless telegraphy systems like ship-to-shore communication based on spark gap transmitters or Morse Code beacons. There were many different types of radios that came out throughout time with one main objective in mind which was to provide the most convenient way possible to listen to radio stations over long distances without having a wired connection. This is not only because they are usually inexpensive and portable, but also for their convenience. Nowadays, many people own portable radios. While they never took away from home stereos or tabletop models, these portables carried FM music programming into new corners of American culture not previously reached by radio. The popularity of this little device led to a line of successors that eventually included shortwave bands as well as AM/FM broadcasts, and later digital tuning capabilities such as those offered today via HD Radio technology. Pioneer Electronics introduced it’s pocket transistor radio, model TR-001, on November 18th 1958 for $49.95 and became an instant hit. It is interesting how far technology has come since 1941! Portable radios became available for home use in 1958 when Raytheon produced a pocket transistorized radio that cost $49.95 (Transelectric).Īs mentioned above, there are many different types of portable radios on the market today and they all do very different things! Some people prefer to carry around an iPod or MPlayer with them so they can listen to any type of content whenever they want through headphones rather than having it broadcast over speakers like traditional portable radios require. The Walkie-Talkies were used by soldiers during WWII. The first portable radio was called the “Walkie-talkie,” which is where radios got their name (Mitchell). Mitchell in 1941 when he created the first 2-way radio that was small enough for people to carry with them during World War II (Mitchell). There are many different types of portable radios available now, but it is important to know their history in order to understand what they can do now. They are used to listen to music, news, and other content on the go. Portable radios have been around for a long time.
