TechnologyHow Technology Changed Communication From Letters to Video Calls
Communication has evolved dramatically from the 1990s when letters were the primary way to stay in touch, especially for migrant workers from villages like those in Bihar. With no mobile phones or internet, families waited anxiously for postman deliveries. The arrival of PCOs, mobile phones in 1995, and subsequent technologies like SMS, 2G, 3G, and 4G transformed communication to instant voice and video calls, connecting people across thousands of kilometers.
