As previously said, it all depends on the teachers. I believe there are more American English teachers out there than British English, so it seems to be more popular. Plus it is often used in commercials, so it's very popular.

I'm Mid-Western, and we pronounce everything phonetically.

Also, a little off topic, but I recently was told that Chicagoans are the only people with junk drawers and pronounce 'front room' as 'frunch room' sometimes. xDD
Does anyone else have a junk drawer? ._o
