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