Looking back reminds of
us of how much change has taken place in a relatively short time (25 years in
this case). You may also want to look ahead 25

The examples below are selected to be representative and not an extensive summary.
You might look at history sites on the web
to see a much longer listing of events that have occurred throughout history.
You can then develop you own listing and select your own time frame for examples
from the past.
