Remember when TV and radio stations went off the air every night. Some still do.
Here's a collection of old and new signoffs (closedowns fror our friends in the UK and the Netherlands)
First, here is the current sign-off for KBCW 44 Cable 12 in the San Francisco Bay Area. They currently sign-off at about 4 AM for about 1 hour while the station does maintenence. NOTE: During the sign-off, KBCW accidentally switches to KPIX's signal which carries CBS' Overnight News Program, "Up To the Minute" with former KGPE-TV anchor Meg Oliver for a few minutes. Afterwards, the STMPE Color Bars and Tone come on with the stations call letters on the lower thirds. (c) 2008 KBCW-TV/CBS Television Stations All Rights Reserved. No Infringement is intended.
This is the devotion and sign-off for CBS Flagship WCBS-TV/New York. Yes it's 1977. Not the BIG 'stache...
Here is KTUL-TV 8 in Tulsa closing down for the night, with what SHOULD be our National Anthem sung as it should be (God bless you, Ray!)
WBKO/Bowling Green closes out with "My Old Kentucky Home...."
And finally, in this round, a rarity: the audio from WLW-C/Columbus, OH's sign of from 1956! There were slides that were added, many of them from the same vintage.
One final sigoff/closedown. This is how the BBC ended operations on the night that Diana, Princess of Wales, was killed.
