Sir, it not Bangalore anymore, its Bengaluru!

Yes, it happened again. Earlier, there were a few cities in India moving back to their pre-colonial names such as Bombay going to Mumbai, Madras going to Chennai, Trivandrum to Tiruvananthapuram, Cochin to Kochi, Calcutta to Kolkata, etc. Now its Bangalore turn going to Bengaluru (pronounced close to "Benglooru", not "Bengaaluru").
While the rationale behind this is something that will be debated for a long time, businesses and Govt, now need to get their official stationery, visiting cards, web sites, etc. changed to reflect the new name. A pain for businesses and a boon for stationery printing outfits, etc.
Internationally though, given the erstwhile nomenclature Bangalore's reach, it will take a while to getting used to the new name.
