Mid Atlantic Accent/English

While listening to a podcast called Your Brain On Facts I heard about an accent that was invented in the early 20th century called the Mid Atlantic Accent, sometimes it's called Mid Atlantic English.  It's often heard in old radio shows and movies dating back to the 30s and 40s.  The accent was taught and along with actors of the time those who were in the upper classes at that time also learned the dialect.  

Is it used today???  Not really, unless there is a period movie that dates back to the time when it was used and has a focus on film and radio, or upper class.  If your into this sort of thing, that is languages and linguistic history I would suggest taking a look at the Wikipedia Article Mid-Atlantic Accent.  You will get a good idea of how the accent works and there are also some links to clips with actors using the accent.
