1970
1968.
Stopped watching TV 6 years ago.
Same here. Watched evening news in high school (69) and stopped thereafter. At 18, I couldn’t take the daily news fest out of Vietnam. Switched to the WSJ in college, then to FR et al in the 90s.
I actually quit TV entirely in HS and didn’t return until well-produced modern serial shows arrived: Boardwalk Empire, Downton Abbey, Carnivale, House of Cards, Deadwood, Turn, The Honorable Woman, The Americans, Homeland, etc.
Watergate did it for me. 24/7
