The January/February edition of the National Geographic Traveler features an article about Clean Hotels, a web-based directory of hotels that do not carry pornography on demand, www.cleanhotels.com

Phil Burress,[pictured] founder of Clean Hotels, said the Web site has become an invaluable tool for families and businesses.

“It’s a great way to protect yourself,” he said, “from the hard-core pornography that pops up on the TV sometimes.”

According to the article, pay-per-view porn accounts for about $500 million annually for the hotel industry, and that puts travelers at risk.

“If your children are in the hotel room… they access it with just two clicks of a button,” Burress said.
