In short, it is a hotel staffer who helps guests with software and hardware problems. More specifically, this title refers to a job position at the Ritz-Carlton hotels, where guests can call upon the "technology butler" to help them with any computer problems they may face while traveling.
The first American technology butler on record is Mr. Michael D'Anthony, who also developed the companywide program. He says "Everyone's on the Internet now, and everyone needs their e-mail. When they travel they run into problems. Either they can't plug in their computer, or they don't know how to change the settings on their computer, or they can't figure out how to get their e-mail, or whatever." People have even called him "Jeeves" in reference to the butler icon on the Web site "Ask Jeeves."
