I found this under the Humor section at Senior Resource:

The people who are starting college this fall across the nation are too young to remember the space shuttle blowing up.
Their lifetime has always included AIDS.
Bottle caps have always been screw off and plastic.
The CD was introduced before they were born.
They have always had an answering machine.
They have always had cable.
They cannot fathom not having a remote control.
Jay Leno has always been on the Tonight Show.
Popcorn has always been cooked in the microwave.
They never took a swim and thought about Jaws.
They can’t imagine what hard contact lenses are.
They don’t know who Mork was or where he was from.
They never heard: “Where’s the Beef?”, “I’d walk a mile for a Camel”, or “de plane Boss, de plane”.
They do not care who shot J.R. and have no idea who J.R. even is.
McDonald’s never came in Styrofoam containers.
They don’t have a clue how to use a typewriter.

The problem is that all those things are much more true than they are funny. The world is changing so quickly now that most of the population do not know what life was like before the invention of television. Notice that the majority of the points made up there have to do with entertainment - and the television has been the most important single factor in the explosion of entertainment that occurred in our lifetimes.

Every generation sees change; new ideas and inventions have always come along and altered the way we see the world. But our generation has seen more change than any other and most of it has been through the television. If the pace of change continues to accelerate, what will the world be like fifty years from now? And will new generations not understand things that were common knowledge only ten years before their time?

Sometimes I look ahead to such things and am glad that I won’t be there to find out the answers.
