There is no doubt that the quality of individual programmess on TV is better now than ever before. We have loved watching series like True Detective, The Wire, The Crown, Stranger Things and some of Brooklyn 99 (Although we’re not sure about the one that takes it to Florida). We still enjoy watching movies and documentaries. But there isn't the same shared experience of the television in my childhood.
I grew up in the 70s when there were only three channels in England and it was a big deal when Channel 4 opened in the 1980s. But anything that was any good became a topic of discussion the next day. And I was lucky enough to be living in the USA in 1990/91 when Seinfeld was just getting going. That was a fantastic program to talk about at the lunch table.
Now that we are spoiled for choice it seems that watching TV isn't as fun as it used to be.
