The history of radio goes back more than 100 years. But still, Radio continues to be one of the most trusted and far-reaching mediums of communication in the world. During this Covid pandemic, it's the medium of education for rural and poor people who either couldn't afford the advanced technology or there is no internet connectivity.
It all started off with a young Italian named Guglielmo Marconi who invented “the wireless telegraph”. He used radio waves to transmit Morse code and the instrument became known as the radio. In 1895 he successfully sent and received a telegram over the first radio signal.
In 2011 the member states of UNESCO proclaimed February 13th as World Radio Day (WRD), as it was the anniversary date of the UN international broadcasting service, which was created on February 13, 1946. It was adopted by the United Nations General Assembly in 2012. On January 14, 2013, the UN General Assembly formally endorsed it.
As an Indian, I would like to trace the history of radio broadcasting in India. It traces back to August 1920 when one of the first radio broadcasts was transmitted from the roof of a building and in 1923, the first radio programme was aired by the Radio Club of Bombay as a private venture. After a brief while, it was shut down and some other players tried their hand. However, things didn’t work out. Finally, the government took over the broadcasting facilities and began the Indian State Broadcasting Service (ISBS) on April 1, 1930. This went on to become All India Radio (AIR) on June 8, 1936. When India became independent in 1947, AIR - was renamed Akashvani. Current PM Modi's "Mann ki Batt" is one of the popular programs in India.
