The communication before radio was very slow, taking months to deliver messages over long distances. In the 1800s, systems like signal lights and the Pony Express sped up communication but were still limited. In the 1890s, inventors like Marconi, Fleming, and de Forest experimented with wireless telegraphy and radio waves, eventually achieving the first radio broadcasts. Radio became an important communication tool in the early 1900s and was vital for rescues at sea. All India Radio was established in the 1930s and was the sole broadcaster until the 1990s when private FM radio was introduced, growing the radio market.
