Although the city is a frequent backdrop for many television shows, many 80s sitcoms set in San Francisco (such as "Full House") were actually shot in studios in the Los Angeles area. Since the mid-90s, many productions supposedly set in the City by the Bay are actually filmed in Canada, most notably in Vancouver, a frequent double for the cities of San Francisco and Seattle on the small screen. Canadian provinces often offer attractive tax incentives and more flexible union regulations for production companies.
