Alta Vista did do enterprise search for a while. I remember in 2003-5 we had a large company choosing between Alta Vista and a Google appliance, the two players at the time. We were pushing them to go Google but they went Alta Vista. Worked decently well though, good search and decent API, the Google appliance was more black box at the time and Alta Vista was kinda flexible/customizable. So they had that.

Also Alta Vista Babel Fish was one of the first good translation services.

Time travelers from the year 1997. Not a big demo.

John Titor still uses AltaVista.

Doubtful. John Titor traveled back in time from the future so if he remains in his past, he likely changed his search preferences with the native people.

I cannot think of a good example right now of someone who traveled from the 1990s to the 2010s or so, although this guide could be helpful: http://en.wikipedia.org/wiki/List_of_television_series_that_...

Non-timetravelers who might be within that demographic are people who just woke up from 15-year comas, people formerly cryogenically frozen, people leaving prison (that doesn't allow Internet access), etc.

The Terminator TV show had Sarah+John Connor jump from 1999 to 2007 in the first episode.
