<P> Studies have indicated that the heavy use of South East England accents on television and radio may be the cause of the spread of cockney English since the 1960s . Cockney is more and more influential and some claim that in the future many features of the accent may become standard . </P> <P> Studies have indicated that working - class adolescents in areas such as Glasgow have begun to use certain aspects of cockney and other Anglicisms in their speech . infiltrating the traditional Glasgow patter . For example, TH - fronting is commonly found, and typical Scottish features such as the postvocalic / r / are reduced . Research suggests the use of English speech characteristics is likely to be a result of the influence of London and South East England accents featuring heavily on television . For example, the popularity of the BBC One soap opera, Eastenders . However, such claims have been criticised . </P> <P> Certain features of cockney--Th - fronting, L - vocalisation, T - glottalisation, and the fronting of the GOAT and GOOSE vowels--have spread across the south - east of England and, to a lesser extent, to other areas of Britain . However, Clive Upton has noted that these features have occurred independently in some other dialects, such as TH - fronting in Yorkshire and L - vocalisation in parts of Scotland . </P> <P> The term Estuary English has been used to describe London pronunciations that are slightly closer to RP than cockney . The variety first came to public prominence in an article by David Rosewarne in the Times Educational Supplement in October 1984 . Rosewarne argued that it may eventually replace Received Pronunciation in the south - east . The phonetician John C. Wells collected media references to Estuary English on a website . Writing in April 2013, Wells argued that research by Joanna Przedlacka "demolished the claim that EE was a single entity sweeping the southeast . Rather, we have various sound changes emanating from working - class London speech, each spreading independently". </P>
