I’m noticing this trend in mainstream media more and more.
It annoys me a little.
I know the word has been around since Aristotle , but the word itself seems to be heading the way of the rarity of Epics in WOW. – Totally too freely used and available. Come on! Epic DVD’s ( and no its not referring to the types of dvds being sold, but to the sale.
The sale is Epic. Lame.

I think they’re just trying to find something new to replace the words that no longer ‘pop’:
“New and Improved”
“Limited Time Only”
“Exclusive”
“Special Offer”
etc.
I’m not saying I like EPIC any better, but at least it’s something different 😛
that is pretty lame.
