It happened that one of my TVs died and needed to be replaced quickly because my daughter and grandson would be visiting. Since it was the one in the guest room -- the TV least frequently used -- I decided to replace it as inexpensively as possible. Fortunately Circuit City was having a sale on all of their TVs. The TV that I was replacing was housed in a built-in bookcase unit with an 18" by 18" opening, and had a 27" viewing screen.
When I got to Circuit City, I was confronted by a sea of flat-screen high-definition TVs. and told that they were the only kind available. My beloved analog TVs were obsolete. It turns out that the only option I had to fit into my allotted space was a 26" flat screen high- def Sony. Since I don't have high-definition reception and when you view non-high def transmission on the full width screen, It truncates the visual, I decided to block the sides, which then reduced my viewing screen to 21".
The result is that I have just spent a lot of money to replace my 27" screen with a 21" screen. I am feeling ripped-off. In order to calm down my anger towards the TV industry, my grandson tells me that in three years all programming will be in high-definition and then I will really appreciate my new TV. That alone encourages me to live that long.
