I only know it as double-U.

I'm form the west so we pronounce it double u.

Double U. You moron.lol

Er...Double U. I may start pronouncing it as 'Dubya' just for the fun of it though. It would sound RIDICULOUS in my accent.

1) The standard, classical way to pronounce it is "double-u". However, some alternative pronouciations such as "Dubya" also exist (for instance in "George W. Bush"). "Dubya" is American English, Texas dialect. 2) "W is the twenty-third letter in the Latin alphabet. Its name in English is spelled double-u." ""Double U" is the only English letter name with more than one syllable. This gives the nine-syllable initialism www the irony of being an abbreviation that takes three times as many syllables to say as the unabbreviated form. A few speakers therefore shorten the name "double u" into "dub" only, although this is rather rare and nonstandard; for example, University of Washington and University of Wyoming are both known colloquially as "U Dub". One alleged use of "dub", however, occurs in the name of the automobile company Volkswagen, abbreviated VW and occasionally pronounced "V-Dub". In the Texas dialect of American English, the name is often condensed to two syllables rather than three, as in George W. Bush's nickname of "Dubya". In recent years, people with last names that begin with "W" frequently received a nickname consisting of their first initial combined with "dub." This may have been popularized by basketball players such as Chris Webber (C-Dub). The fact that many website URLs still require a "www." prefix has likewise given rise to a shortened version of the original, three-syllable pronunciation. There has been an increasing move away from the three-syllable pronunciation as a result; the "dub" pronunciation vies with a "wuh" or "wub" pronunciation. A third, and perhaps more phonetic, pronunciation 'wah' (/wÉ”/) has begun to enter usage in certain literary circles, justified as being a more natural method of verbally expressing the letter. In Dutch, its name rhymes with that of the letter v, both being monosyllabic (fe/ve/we)." Source and further information: http://en.wikipedia.org/wiki/W

I pronounce it 'dubya', and I grew up in southwest Missouri (missour-ah). It is just a question of accent, neither right nor wrong. Just as the northern cities vowel shift has distorted many words, such as 'bad' (be-ad), 'man' (me-an), as examples. Again, it is an accent, and everyone has an accent.
