Tropes/Network Finale

A network gives itself a proper farewell before its Network Death.

Cable/Satellite TV Channels

 * April 25th 2022, the day Adult Swim was to stop airing in France, was marked by the airing of the supposed bad ending of Pibby (revealed to be a mere fan-animation), followed by episode after episode being taken over by the series' villain, the Glitch, and ending with the "last" episode of Robot Chicken as the grand finale, followed by all the characters of the channel's shows emerging from the Glitch blob. After the channel was shut down, the only text that ever appeared on-screen was a (fittingly-glitchy) No Signal-style screensaver that said: "CETTE CHAÎNE A ÉTÉ CORROMPUE PAR LE GLITCH. [adult swim] NE DIFFUSERA PLUS. TOUS SALUENT LE GLITCH."
