Correct Ans: (A)
Explanation:
The development of radio communication in India follows a chronological order marked by significant milestones. The journey began with All India Radio (AIR), which was established in 1936. AIR, originally known as the Indian State Broadcasting Service, became the cornerstone of radio broadcasting in India, serving as the government’s medium to reach the masses with news, education, and entertainment.
The next major development was the introduction of FM radio in the 1990s, which offered better sound quality and more diverse programming than the traditional AM stations. FM radio stations became immensely popular in urban areas due to their clearer sound and music-centric content.
Following FM, Digital Audio Broadcasting (DAB) emerged as an advanced form of digital radio, offering even higher sound quality and the ability to broadcast multiple channels on a single frequency. DAB’s adoption has been slower compared to FM, but it represents a step forward in radio technology.
Finally, Internet Radio began gaining popularity in the 2000s with the advent of the internet. It allows users to stream radio stations or personalized channels online, overcoming geographical boundaries. This has opened up new possibilities for radio communication, making it accessible globally.
Thus, the correct sequence is: AIR – FM – Digital Audio Broadcasting – Internet Radio.
