Tour Guides for Virtual Tours...Google Mars project for a tour to the outer space or Arounder.com for a hike to the top of the Matterhorn are just few samples. 

However, most virtual venues are far from exotic; virtual tours often fulfill practical, everyday queries about a potential destination - such areas of personal interest as colleges and universities, tourist and vacation locales, historical sites, museums, real estate, and hotels.

And who are most likely to go on virtual tours:

• 57% of people in the 30-49 age bracket have taken virtual tours, compared with 47% of those ages 18-29 and 29% of those ages 65 and older. 
• 61% percent of college graduates have taken virtual tours, compared with 41% of high school graduates. 
• Those with household income of $50,000 or higher are also more likely to have ventured somewhere online than those with lower household income (64% vs. 41%).

• 62% of home broadband users are virtual tour takers, compared with 41% of home dial-up users. 

• Some 60% of internet users with six or more years of online experience have taken virtual tours, while only 28% of those with two to three years of online experience have done so.

• Internet users who are parents of children under 18 at home are more likely to have taken virtual tours than those who have no children under 18 (58% vs. 47%)

These findings come from a nationwide telephone survey of 2,928 adults by the Pew Internet & American Life Project in August 2006. The portion of the survey that covered virtual tours was administered to 1,018 internet users.
