First started by two roommates as a way to make some quick cash by selling crash space in their San Francisco apartment for an upcoming international design conference, Airbed and Breakfast is now a hospitality company helping people find places to sleep all across the world.

The company is described by the Wall Street Journal as occupying "a space between couch surfing and large hotels," putting it in competition with traditional bed and breakfasts and urban vacation rentals.

The company now has a website, AirBnB.com, where, in their own words they "enable people to earn money by renting out extra space, and offer travelers a viable alternative to hotels."

Originally they started by focusing on events, such as the Democratic National Convention in 2008, but now the focus has switched to cities. The community aspect of the site lets people rate guests and hosts, so a guest can choose to only stay with a high-rated host and a host can choose to only rent to high-rated guests.

Currently, the site boasts that you can rent nightly rooms in 1,026 cities in 76 countries.

Careers in hospitality are plentiful, according to the Bureau of Labor Statistics. Hotels and other accommodations provided 1.8 million wage and salary jobs in 2006.
