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.
New England
There are several American English accents spoken in the region (normally north of Connecticut), including New England English and its derivative known as the Boston accent, which is native to the northeastern coastal regions of New England. The most identifiable features of the Boston accent are believed to have originated from England's Received Pronunciation, which shares features such as dropping the final R and the broad A. Another source was 17th century speech in East Anglia and Lincolnshire where many of the Puritan immigrants originated. The East Anglian "whine" developed into the Yankee "twang". Boston accents were most strongly associated at one point with the so-called "Eastern Establishment" and Boston's upper class, although today the accent is predominantly associated with blue-collar natives, as exemplified by movies such as "Good Will Hunting" and "The Departed". The Boston accent and those accents closely related to it cover eastern Massachusetts, New Hampshire, and Maine.
