In the early days of television (about seventy years ago) there were few choices. On our black and white receivers, we could select shows from 3 or 4 local channels. All were all free. Making viewing decisions was easy with so few choices. Television sets were expensive, so most homes had only one.
We needed rabbit ears or a tall roof top antenna to gain a signal. Out television sets were full of vacuum tubes that were housed in a large, heavy cabinet. Screens were no larger than 21 inches. Repair service was required frequently. Daily test patterns (available early before the broadcasting day began and late after the day ended) allowed for our sets to be adjusted. During the viewing day the picture would roll over vertically or blur horizontally. We would jump up to adjust. There were no remote controls or DVRs.
Television has changed. We can now watch on several devices like cell phones and tablets. We may have an 86-inch, flat screen television set that covers the entire wall in a room arranged for viewing from large reclining chairs. Other sets can be sprinkled around the house into bedrooms and the kitchen; no need for the family to be in the same room watching the same shows. Many of these are SMART television sets. A reader who does not own a SMART set can stop reading here. You have some catching up to do before reading about or signing up for the latest advance in television: STREAMING!
The linked article below is helpful. It clearly guides us in making life-changing decisions concerning which receivers to purchase and which streaming services to pay for. You go first. I will await your call as to what I should do about this. For now, I am content to allow others to lead the way. Please hurry in making your assessment because, like many, we may stop watching television all-together. Library books and music are free and appealing.
