Why are people who write for the media, advertising, etc. unable to master the possessive and correct use of the apostrophe!!!??? Do these poor hacks think they'd better use that apostrophe-s just in case not using it would be a big blooper?

Am I the only person in the world driven to distraction by seeing the possessive wrongly applied?

Is this a losing battle just like the already lost battle of "there is" when "there are" should be used?
