You have brought up an oft overlooked bias on the part of the presenter.
Some elements of style are cultural: the use of the apostrophe being a a great example.
Starting in the 1950's British newspapers dropped the apostrophe in the pluralization of abbreviations. It has since become common practice (practise in the UK) in the non-US English speaking world.
The United States on the other hand still frequently uses the apostrophe to indicate the missing letters.
So, the moral is to know your audience. If you are presenting:
Years: 1950s UK, 1950's US
Abbreviations: COOs UK, COO's US
Spelling: Colour UK, Color US
And, if you are an audience try to be considerate of your presenter, and focus on the message, not the grammar.
