Those who are old enough might remember the days where you lived in a house that had no telephone. When you want to take a call you went to post office or a public place where telephone facilities are available. In India, Sam Pitroda’s name went into history for the ubiquitous, yellow-signed Public Call Offices (PCO) that enabled cheap and easy domestic and international public telephones all over the country in 1980s. Nearly two decades later the rapid expansion of mobile phones has finally brought that era to an end. Not surprisingly, public pay phones are rarely used these days.
