Q: When did the TV show Twin Peaks go off the air?
A: June 10, 1991
I found this answer by going to google. I typed in twin peaks imdb and clicked the first link. From the IMDB website, I went to the full episode list and found that the final episode aired on June 10, 1991. It was episode 22 of season 2, to be more specific.
From the video we watched on Monday, I learned that people were content with their communication systems prior to the internet and that that computer communication was not a big deal. I was also surprised that the internet was responsible for 1/3 of economic growth in 1998.
