The twentieth century had more than it's share of dubious "innovations"; atomic weapons, the wonder bra and (of course) new Coke. The worst of the bunch, though, has to be twenty-four-seven wall-to-wall news coverage.

In the early days of television -- when most of the sets were still pedal-powered -- there were only three networks and respectable men like Walter Cronkite stared into the camera with sincere expressions and read the day's news to us like a patient teacher reading to a class of dim-witted students. Walt stuck to the facts and gave us the stories in one quick dose; sort of the way you give nasty-tasting cough syrup to a child.

Somewhere along the line the TV networks decided that we were too dense or busy or distractable to absorb ... um ... what was I talking about?

Oh. Right. As a result of years of exposure to fast-paced TV shows, we no longer had the attention span necessary to ... hey, is that a butterfly?

Sorry. I meant to say that we could no longer focus on the news the way Walt delivered it. We still needed quick doses, but we needed them over and over and over. The motto of the modern television news industry is "It's not done until it's overdone!".......

The origins of defense contracting are shrouded in the mists of history -- or at least cloaked by the Official Secrets Act. I'll bet, though, that the original defense contractors were the guys who came up with the Swiss Army knife.

Really.

The Swiss Army knife inconveniently combines unrelated tools in a package which is simultaneously too small to be useful and too big to comfortably fit in your pocket. Only an experienced, dedicated design committee could have created a device which promises so much and delivers so little. Then they made a fortune by selling it to the Army. I'm sure these guys were the ancestors of the people who created the Osprey Vertical-Take-Off-and-Landing aircraft. Not all of these guys work for Defense, though. A fair number of these "jam it together and see what sticks" designers work in cell phone manufacturing.......

For on-going, ever-changing, cheap home entertainment, nothing beats having children. Well, not cheap exactly. If you're planning to have a child, you'd best be prepared to pay medical costs, daycare, the cover prices for a vast array of comprehensive parenting manuals which contain mutually-contradictory advice, pre-school testing fees, school enrollment fees, school picture fees, school picture retake fees because the first set of pictures make your child look like a member of the marsupial family, fashionably-ripped clothes, new fashionably-ripped clothes because the old ones aren't fashionably-ripped enough, driving lessons, a new car to replace the one which was tragically lost at sea during the driving lessons, car insurance against the next unforeseen disaster, orthodontia, eye wear, personal technology, SAT study guides, ACT study guides, study guides for re-taking the SAT and the ACT, professional tutoring for the SAT and ACT, bribes to get college admissions officers to look the other way when they see the SAT and ACT scores, college tuition, college graduation costs, and a parental subsidy for the first post-college year as your offspring try to establish themselves. All things considered, the cost of raising a child to productive adulthood is comparable to the cost of the average space shuttle mission, but with far less chance of being featured on the national news. (Although, in an interesting coincidence, if you do have children it's a good bet that just like the astronauts, they will lose one-hundred-thousand dollars worth of tools before they move out.)......
