London
There are many accents traditionally associated with London. The most well known of the London accents long ago acquired the Cockney label from London's East End, which is heard both in London itself, and across the wider South East England region more generally. The accent of a 21st-century Londoner varies widely; what is becoming more and more common amongst the under-30s however is some fusion of Cockney with a whole array of ethnic accents, in particular Caribbean, which form an accent labelled Multicultural London English (MLE). The other widely heard and spoken accent is RP (Received Pronunciation) in various forms, which can often be heard in the media and many of other traditional professions and beyond, although this accent is not limited to London and South East England, and can also be heard selectively throughout the whole UK amongst certain social groupings. Since the turn of the century the Cockney dialect is less common in the East End and has 'migrated' east to Havering and the county of Essex.
Culture of New England
The New England English dialect and Boston accent are native to the region. Many of its most stereotypical features (such as r dropping and the so-called broad A) are believed to have originated in Boston from the influence of England's Received Pronunciation, which shares those features. While some Boston accents are most strongly associated with the so-called "Eastern Establishment" and Boston's upper class, the common accent is locally prevalent and predominantly associated with blue-collar natives exemplified by movies like "Good Will Hunting" and "The Departed". The Boston accent and accents closely related to it cover eastern Massachusetts, New Hampshire, and Maine.
