Bombay was renamed Mumbai.
Bangalore became Bengaluru.
Calcutta switched to Kolkata.
Why are we seeing new names for old Indian cities?
So why are these cities switching? Turns out, British rule played a large part. Kolkata was British India's former capital, but the British called it Calcutta.
Now, even decades after Britain released its grip, India is still trying to get back to its roots.
But just because a city changes its name doesn't mean natives follow along.
Mumbai, for example, is still often called Bombay or Mumbai, interchangably.
As for the most recent change to Gurugram, plenty of Indians on Twitter are making fun of the switch.
