#8. TV station signing off
Before infomercials were invented, television stations actually went off the air for a few hours each night. Some of us TV-holics experienced physical withdrawal symptoms when we heard the announcer intone, “We now conclude our broadcast day…” around 2AM or so. The format varied little from station to station across the country; first a few technical details were announced, then a reading of “High Flight” followed by the National Anthem, and then the steady beeeeeeeeeeeeeep tone of the test pattern.
