Tropes/Network Finale

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

(Laconic description)

Broadcast TV Channels

 * A strange example with Patagonian Educational Television (PET). The network had long been suffering from Network Decay, but in 2010, a major studio fire forced it to shut down for good. After the studio was evacuated, PET's master control was set ablaze and, for the only time on Patagonian television, the computer-generated caption was replaced by a killscreen-style caption, reading out "COMPONENT FAIL - BOOT NOT FOUND - CONTACT TECHNICAL SUPPORT" stating that the components of hardware used to generate the caption had failed from them being fried in the blaze. The caption stayed until the signal was lost when the transmitter collapsed.
 * Channel 7 was the Singaporean public broadcaster Mediacorp's failed attempt to expand into Borneo. Lack of funding from the Singaporean government and the slow death of the TV license fee in Borneo led to the channel's collapse in 2008. But it did go out with a bang, with the ominous visual of Channel 7's cubic ident turning grey and disintegrating and the white and blue background fading to black, accompanied by Raimundo de Costa's somber announcement that the network would shut down. This would be followed by the corporate logo animation and the Bornean national anthem.

Cable/Satellite TV Channels

 * April 25th 2022, the day Adult Swim was to cease broadcasting in France due to its sale to Canal+, went like this:
 * The downbeat "finale" of Pibby, which was very obviously a fan animation, involving Pibby's defeat and assimilation.
 * Episodes of Rick and Morty, Secret Mountain Fort Awesome, and the like getting taken over by the Glitch as a consequence.
 * A final montage showing all of Adult Swim's past cartoons falling victim to the Glitch, culminating in all the characters of the show's series (Pibby, Festro, and the RC Nerd included) emerging as assimilated zombies.
 * The final announcement (accompanied by an appropriate soundtrack) stating that after 11 years, Adult Swim would no longer broadcast in France, and thanking its viewers for tuning in, before ending in assimilated!Pibby pulling off a jumpscare.
 * And to wrap things up, the screensaver-style caption (with distorted and/or lettering) stating that Adult Swim had ceased broadcasts in France, constantly glitching due to the Glitch having finally taken over.
