TFTP Special: Sign-Off on WTVJ (Miami) (1980)

The very first TFTP post a few weeks ago was a TV station sign-on used at the beginning of the broadcast day. Here is its counterpart, a sign-off, the segment of programming at the very end of the broadcast day--from when stations used to actually sign off and go off the air overnight. Many sign-offs included a brief news update (this one does not) and they almost universally featured a brief film or tape segment of the U.S. national anthem (as this one does). This sign-off from 1980 also includes a few program promos (including for a CBS TV broadcast of the movie "Rocky") and a couple of public service announcements (PSAs), which stations often loaded into this late-night period.  It's from station WTVJ in Miami, Florida's first TV station (launching in 1949), which at this time was on Channel 4 and was a CBS affiliate but has since switched to Channel 6 and NBC.
