Hollywood done with southern reality shows

            An industry source tells us time have changed, and studio doors are locked tight when new Southern shows come a-knockin.' Networks were gunning to cram their programming hours with salt-of-the-earth Southern fare, also affectionately known as redneck reality television. Moonshiners, duck call makers, backyard oil drillers. If the shows featured good-ol southern characters, the shows got the green light. Nowadays, an industry source tells us time have changed, and studio doors are locked tight when new Southern shows come a-knockin.' The market just got saturated and development execs are all looking for next big thing, the well-placed insider told FOX411's Pop Tarts column. Shows set in the South have seen phenomenal success over the past few years, and TV viewers have showed up by the millions to get a glimpse of the south. That being sad, more recently we've seen that a lot of networks are trying to veer away from the south in the new shows they're developing
               The current reality TV landscape- which includes A & E megahit "Duck Dynasty", History Channel's Swamp People," CMT's "Redneck Island", and Discovery's "Backyard Oil" and "Moonshiners" may soon be but a memory. And according to Hollywood agent Alec Shankman, once the shine wears off a reality genre, it's only natural Hollywood will seek something new to get tongues wagging. "The perception of creating' derivative' programming can influence TV buying decisions and cause a change of course, ' he said. "Hollywood is cyclical by nature. Sitcoms are in, then they're out, then they're back in. Game shows are in, and then out, then back again. The same applies to genres of reality TV." For example, a decade ago it was all about competition shows like MTV's "Real World" and "Survivor", then attention shifted to Paris Hilton and her "Simple Life" as Jessica Simpson and Nick Lachey's tribulations in "Newlyweds," before moving to "finding love" shows like "The Bachelor" to the shop-happy rich people in "Real Housewives" and "Keeping Up With the Kardashians."
