Struggling Broadcaster

Usually Played For Laughs in comedy, the Struggling Broadcaster is a station with heart, but with no ratings to speak of and usually a low or nonexistent budget. It's run by a skeleton crew whose antics are more fun than a barrel of monkeys; every one at the station wishes you'd tune in but the deck is stacked against them for any of a number of possible reasons:
 * The station is broke or going bankrupt. The paycheques are bouncing, the announcers are begging for donations on-air in a telethon just to keep the show alive. If it's a non-profit educational outlet, the scoreboard during a PBS-style pledge break might actually show a negative number (perhaps to reflect the station spent money it doesn't have just to rent the board for the donation drive).
 * The station is a low-budget independent, while its competitors are on better spots on the dial and backed by the stronger programming resources of the major networks. With limited resources and no budget to acquire batter content, the only programming (other than minor-league sports matches and old public-domain movies) is Cloudcuckoolander nonsense which the station produces itself – on a shoestring.
 * The station is on a high UHF channel in an era before manufacturers were legally required to include UHF tuners on every TV set. Of the first hundred pioneering American Television Stations who took a chance on UHF when the US FCC opened channels 14-83 for over-the-air broadcast in 1952, eighty were defunct within the first year. Without any viewers, they couldn't get the network affiliation or the advertisers; without the network's programming, they couldn't get the viewers. If they had managed to get a network feed, they lost that affiliation to the first competitor to launch a VHF station. If no one could see the station, no one noticed when it silently went dark and never came back.
 * The station is underpowered. On the medium-wave AM radio band, it may on a "daytime" frequency on which it has to drop power or go completely off the air at sundown to protect a distant broadcaster on the same frequency. On FM or TV, it may be have acquired the licence by buying an existing low-power "repeater", "rebroadcaster" or "translator" (which normally just provides a fill-in signal where there are gaps in a full-service main station's coverage) and re-purposing that allocation for an originating station.
 * The station is licenced to serve a tiny or distant village, from which it can barely reach the larger city as a "rimshot", but isn't taken seriously as the announcers, the listeners or both are Hee Haw-style hillbillies.
 * The station's management may be dishonest, or actively harming the operation in some manner. Maybe they're alcoholics. Maybe they're mentally ill. Somehow, the staff tries to stay on the air and beneath the radar of the national broadcast regulator even though the entire operation is too dysfunctional to be viable.
 * The station may be on the air just to keep the licence active, or so that the money it loses can be written off against taxable income from some unrelated venture. For local cable access television channels, the content has to exist as a condition of the parent CATV operator's licence, but the owner likely does not care that no one is watching.
 * The station is badly short-staffed, either on a permanent basis (due to lack of funds) or temporarily (it's in a mountain community and none of the regular announcers made it in through an exceptionally-harsh blizzard, so as an unexpected one-person show the only one to arrive is expected to fill an entire thirty-minute time slot pretty much ad-lib).
 * The station is staffed by people who are simply incompetent.

Invariably, in the finest traditions of Captain Video and the long-defunct DuMont Television Network, all of this No Budget content goes out live – warts and all.

Evidently, the Struggling Broadcaster has to be strong enough to be originating content (instead of merely rebroadcasting another station, or playing audio or video unattended using broadcast automation) for the trope to work. Among local originating stations, though, this one will invariably be in last place - and likely have been there, unnoticed, for years. Eventually, someone decides that there is No Such Thing as Bad Publicity and having audiences laugh at the station's expense is somehow better than going silently off the air and into the night.

Film

 * UHF (1989) is a "Weird Al" Yankovic comedy about a lad whose uncle wins an underpowered, low-budget independent local UHF 62 station in a poker game. The stations ratings are in the toilet until the station's janitor goes on-air with Cloudcuckoolander antics bizarre enough to give an audience a reason to tune in.
 * Videodrome (1983) follows the CEO of a small independent UHF station (CIVIC-TV 83, as presumably a parody of CITY-TV 79 Toronto) who stumbles upon a satellite signal that is broadcasting extremely violent and horrific things. He makes the mistake of rebroadcasting the content, which harms the local community.
 * Wayne's World (1992) is a comedy film, based on a Saturday Night Live routine, about the hosts of an Aurora, Illinois-based cable access television show who attempt to do their jobs despite Executive Meddling by corrupt higher-ups in the organisation.

Live-Action TV

 * Monty Python's Flying Circus had an episode depicting the BBC running out of money. Characters appearing in comedy sketches were begged on-air not to speak because a speaking part gets paid more; someone utters one word and it's "oh dear, that's fifteen shillings out of the budget" that poor auntie Beeb can't afford. The credits were written on scraps of paper and the heat was turned off in the flat they were renting as a studio.
 * Mork and Mindy has title character Mindy McConnell as an inexperienced new hire at a television station owned by an intoxicated old man whose local farm report was getting unprecedentedly poor ratings until he tried on-air to milk a bull. After being given the job for little more than a complaint of "why do you ask for experienced people, when no one's willing to give anyone any experience?" she's basically plopped behind a live news anchor desk during a blizzard and invited to fill a thirty-minute prime-time news broadcast with basically no advance preparation, solo.
 * WKRP in Cincinnati is based around an AM radio station which was dead last in ratings after playing endless elevator music for years. In desperation, and to listeners' disbelief, the station abruptly changes format to start blaring Rock and Roll. Not the first Mary Tyler Moore show to be based on a dysfunctional broadcast newsroom, but WKRP was unusual in that the vinyl spinning on-air in the original broadcast contained a few real hits, current and popular at the time. (This created some issues when trying to create reruns or DVD box sets later.)

Theatre

 * It's a Wonderful Life: Live From WVL Radio Theater is a touring theatrical piece about a handful of fictional station "WVL Radio" staff who somehow make it through a blizzard to get to the radio station, where they have to put together a live Christmas Eve rendition of the classic plot with very few voices, none of the station's experienced actors on hand and whatever meagre props or sound effects are available. As it's a story about presenting a well-known story, it differs from all of the classic 1940's radio broadcasts which predated the 1948 It's a Wonderful Life feature film and which played the story straight.

Real Life

 * The DuMont Television Network (1946-56) was a hopelessly low-budget fourth terrestrial network in an era when most major cities only had two stations at best – and those stations mostly chose to affiliate with NBC or CBS because those were already the firmly established brands on network AM radio. There were no broadcast videotape recorders until 1956 (by which time the network was dead) so, by necessity, most content went out live – and the rest showed up at the individual stations as reels of movie film. Effectively "FOX thirty years before FOX" but run on a No Budget shoestring by a once-innovative manufacturer of television sets who did not survive.
