Have you ever wondered why the short form of 'Bangladesh' is written as 'BAN' in cricket? We see this during the live telecast of matches. The same is written on http://www.espncricinfo.com. We are the only cricket playing nation whose short name (BAN) actually forms an English word which has a negative meaning.
The English word 'ban' means 'an official order that prevents something from being used or done,'  'expel from a community or group,' or 'prohibit especially by legal means or social pressure'. It's not that they use the first 3 letters of a country's name in case of all countries: Sri Lanka is not written as 'SRI' but 'SL'; New Zealand is not written as 'NEW' but 'NZ'.
My point is, since the word 'BAN' has a negative meaning, why not shorten the name Bangladesh as 'BD' or 'BGD'? We've got so many people in the Bangladesh Cricket Board (BCB) and there are former cricketers, commentators, politicians, journalists, fans; why hasn't anyone ever raised this question? Why haven't we ever felt offended? Why haven't the Bangladesh cricket fans ever protested?
