As digital transformation and digital platforms came together, radio became the main medium for entertainment, information dissemination, and cultural representation. This evolution marked another milestone in radio history making FM the ruling technology in India’s media landscape and its deep resonance with listeners all over the country. 

Evolution Of Radio - Technological Advancements

The evolution of radio in India as well as the whole world is led by significant technological improvements in analog radio that introduced the use of a box for entertainment, information, and much more. Here are some of the milestones that explain this complete journey:

1. AM and FM Radio Broadcasting

Both the AM and FM have played a core role in the evolution of radio in India. AM helped to encourage long-distance transmissions of the information to support the radio reach and accessibility, FM radio broadcasting on the other hand contributed significantly to revolutionizing sound quality and providing a better experience to the listeners. 

2. Transistor Radios

The introduction of the transistor radio in the 1950s was another momentous milestone in the history of radio. These were the pocked-sized devices consisting of vacuum tubes. These radios were very cost-effective, compact as well as energy-efficient. This innovation eliminated the constraints of distance and time, fostering a wider reach of radio among the target audience. Also, transistor radios completely reshaped the listening habits of people due to their mobility. 

3. Portable and Car Radios
