Found an off the wall TV program that showed various projects built
from discards headed to the dump.

One was the universal "Off", TV remote.

Starting with an old TV remote, stripped out everything but the "Off"
switch then re-programmed the remote to issue a continuous string
"Off" commands for every TV made.

Next, hide the unit in a hat so that you could walk down the street
wearing the hat and push the "Off" button turning off any TV with in
about 50 ft.

Impressive use of technology by someone with a lot of spare time or a
diabolical sense of humor.
