Newsreaders, speech, grammar and pronunciation

In the 50s and, I think, into the 60s, all newsreaders spoke what was described as the Queen’s English – no regional accents, educated speech and correct pronunciation and grammar. Whether or not a listener had any concept of correct grammar, the fact of listening to people who spoke correctly did, in effect, help teach listeners correct use English. Sadly, it seems to me that the standard has dropped considerably and the daily reminder of how language should be used has, to an extent, gone. This comment should not be taken to imply that I have any issue with regional accents (which are now often heard); the issue is with sloppy speech.
