After the invention of FM radio by Edwin Armstrong in 1933 - the company called General Electric came up with the idea of FM broadcasting in 1940 and showed that FM radio broadcast is better than AM and is less prone to elecctro-magnetic disturbances. Since then people have started using AM receivers. The first temporary radio station and broadcast was done by Guglielmo Marconi in 1895, and after that many radio stations started broadcasting news, music, fiction readings, etc on AM frequencies. Earlier there were only AM radio receivers and people used analog AM radio receivers for listening to news and music.

Analog radio receivers: These types of radio receivers can receive analog radio broadcasts of AM/FM frequencies.Internet radio receivers are also digital radio receivers but can only receive radio stations when connected to the internet.

Among the digital receivers, it can be either an AM/FM HD radio receiver or a DAB/DAB+ receiver.

Under the analog category, there comes either AM or FM receiver but can also be a combo receiver. There are mainly two categories of radio receivers – analog and digital. The technology of radio receivers has changed many times since the invention of the first radio receiver, and the radio receivers are becoming smarter with the advent of various new technologies. Such SDR radio receivers became popular among the ameture radio enthusiast and the USB dongle with the Realtek RTL2832U/R820T2 demodulator chip is often used by such enthusiasts as an SDR receiver. This became possible after the introduction of System-on-a-Chip (SoC) fabrication technology, and the first SDR receiver was made with the BCM21551 processor by Broadcom in 2007. An SDR receiver is a radio receiver which can receive both analog and digital radio transmission but can be configured and controlled using software.

This change in the technology of radio receivers even went beyond internet radio – after the arrival of Software Defined Radio (SDR). Kerbango internet radio receiver from 3com was the first standalone internet radio receiver of 21th century. An internet radio receiver can be either an app of a computer or can be a standalone receiver, connected to the internet to receive internet radio stations. However, radio receivers became diversifying when internet technology was implemented in them, which made it possible for the companies to introduce internet radio receivers. In 2003, Pure launched the PocketDAB 1000 and It was the world’s first pocket digital radio capable of playing DAB radio stations. After the emergence of digital electronics and digital radio transmission, digital radio receivers started to capture the market – receivers capable of receiving Digital Audio Broadcasting (DAB) – digital radio transmission. Scott 350 (1961) came in the market, and they were the first analog radio receivers of that kind. First came the De Forest RJ6 in 1916, and later many analog radio receivers like Sony TR-63 (1957), and H.H. Since the invention of analog radio by Marconi in 1895, many companies started manufacturing radio receivers. A radio receiver capable of receiving any analog audio on AM/FM frequency is called analog radio receiver and for many years people were using analog radio receivers. These frequencies are of two types – Amplitude Modulation (AM) and Frequency Modulation (FM). A radio receiver can receive radio signals of various frequencies by tuning to a particular frequency. A radio receiver is an electronic device that can only receive radio signals and can convert the radio signals to audio and sound. After the invention of radio communication by Guglielmo Marconi in 1895, the first radio receiver was also invented by Marconi. Radio receiver is one such gadget that people have been using for many generations.
