from www.tmz.com – America’s obsession with hillbillies is spilling over into the adult industry in a BIG WAY … because sales of redneck-themed porn has nearly TRIPLED in the last two years … TMZ has learned.

The toothless, backwoods, yokel formula has already proven to be a recipe for success in reality TV — spawning hits like “Honey Boo Boo,” “Duck Dynasty” and “Swamp People” … in fact, MTV has already announced plans for an upcoming hillbillly-themed reality show.

Now, one of the biggest websites in porn is also recording record sales in the hillbilly/redneck genre (there’s a XXX genre for everything) … and it credits the boom in sales to the bumpkins on the “mainstream” side of the things.

TMZ spoke with a rep for GameLink.com, who tells us the company has seen a 250% increase in Southern, white-trashy porn titles since 2010 … when the redneck reality shows began to take off.

In fact, we’re told prior to the release of the reality shows, hillbilly porn was one of the site’s worst-sellers. But now, Southern-themed titles like “Hillbilly Honeys,” “Real White Trash” and “Ozark Sex Fiend” are RISING AGAIN … with no signs of slowing down.
