Is it OK to drop the periods in abbreviations?
Okay, so in School I was always tought that when we want to abbreviate, we must use a full stop "." inbetween each letter, and if it's at the end of a sentence, a full stop at the end also (duh).
But, everywhere I go now, I am faced with having to put up with bad grammar, incorrectly-spelled words, and just total rubish. And I believe marketing is to blame! Think about it... When was the last time you saw a major company with a nice looking logo like AVC use dots inbetween each letter?
It's become so widely accepted that everybody does it now - all the time. Now I'm getting confused because all I've seen for a long time is just total rubbish, and now I don't remember which way is correct or not.
Say for example the following letters stand for "Another" "Silly" "Word", which version of abbreviation is correct?
A.S.W
A.S.W.
ASW
Or are they all correct?
