Now I grew up in the 50s and 60s and let me tell you, game shows were fun back then. I think one of the reasons why game shows were popular back then was that we saw people from all walks of life trying to win big money. We got to know most, if not all the players from shows like "64,000 Question", "Twenty One" (The Jack Barry version), "What's My Line?", "To Tell The Truth", and even "You Bet Your Life".
Another reason why these shows were popular was that the hosts of these shows (I.E. Bud Collyer, John Daly (What's My Line?), Hal March, and even later people like Jack Narz, Tom Kennedy, and Bill Cullen) were very personable. They gave their shows lots of energy.
A third reason is the play along factor, which still hold true today. In addition, the game shows were very inventive, I.E. Video Village, Seven Keys, Double Exposure, and Camoflauge to name a select few, making the viewer have more fun.
In comparison to today's shows, the 50s and 60s brought out plenty of game shows that were for the most part, fun. Today there are some great games out there. Of course, we still have Jeopardy, Price is Right, & Wheel of Fortune which will be around for years to come and are three great examples of the viewer playing along with the contestants on stage. In the last three to four years, we have Millionaire, which began a trend of really big money games, most of them fell by the waistside, yet some were memorable (Greed and Maury's Twenty One) than others (It's Your Chance of a Lifetime and The Chamber). Then there were the game operas, led by Survivor, which still can't be topped, and talent contests which for the most part look and sound the same.
Overall, the 50s and 60s games had a variety that may not be matched to today's handful of shows. I would love to see another wave of game shows come, different ones that can be fun, and not those game operas that play too much like soap operas.
