Millions of people make a living without ever setting foot in an office. Particularly in technology, companies are moving away from just outsourcing rote tasks to remote workers and toward building entirely distributed teams.

Telecommuting in the United States increased by as much as 79% (paywall) between 2005 and 2012.
