Didn't we go over this a while ago? Aditya or Sujeet or Ulhas probably have better info, but here's my 2c: the rename is part of the right-wing driven effort to "re"claim Bombay as a Marathi city (Bombay is part of the state of Maharashtra, though there is a large Gujarati population). I think this is also part of the ongoing process of renaming Indian cities to their "original" names, which has led to such silliness (IMHO of course) as Madras turning into Chennai (In the case of Madras, as opposed to "Trivandrum" which is a British corruption, the name Madras, short for Madraspatnam, is as valid a name for the city, and the usage by locals has always been to refer to it as Madras in English and Chennai in Tamil).

P.S: Trivandrum, in Kerala, is now once again Thiruvanandapuram [sp?]
