The 1942 short story "The Twonky" by "Lewis Padgett" (Henry Kuttner and C. L. Moore), which originally appeared in Astounding Science-Fiction, September 1942 (available at the Internet Archive), was about a sentient radio-phonograph; however, in the movie adaptation The Twonky (1953), it was changed to a TV:
After seeing his wife off on her trip, Kerry West, a philosophy teacher at a small-town college, goes inside his home to contemplate his new purchase – a television set. Sitting down in his office, he places a cigarette in his mouth and is about to light it when a beam shoots from the television screen lighting it for him. Absentmindedly unaware of what has taken place, it is only when the television subsequently lights his pipe that West realizes that his television is behaving abnormally.
West soon discovers that the television can walk and perform a variety of functions, including dishwashing, vacuuming, and card-playing. When the television deliveryman returns to settle the bill, the television materializes copies of a five-dollar bill in order to provide payment. Yet the television soon exhibits other, more controlling traits, permitting West only a single cup of coffee and breaking West’s classical music records in favor of military marches to which it dances. After West demonstrates the television to his friend Coach Trout, the coach declares the television set to be a “twonky”, the word he used as a child to label the inexplicable.
Trout soon concludes that the Twonky is a robot committed to serving West. When he tests his hypothesis by attempting to kick West, the Twonky paralyzes his leg. After tending to the coach, West attempts to write a lecture on the role of individualism in art, but the Twonky hits him with beams that alter his thoughts and censors his reading. When West attempts to give his lecture the next day, he finds himself unable to do more than ramble on about trivialities. Frustrated, West goes to the store from which his wife had ordered the television and demands that they take it back or exchange it.
Meanwhile, at West’s house, the coach has summoned members of the college's football team and ordered them to destroy the Twonky. West arrives with the television deliveryman and his replacement set, only to find the players passed out in front of the machine. When West wakes them up, they appear to be in a hypnotic state mumbling that they have “no complaints,” a condition the Twonky soon inflicts on the deliveryman as well. Upstairs, Trout theorizes that the Twonky is from a future “super state” that uses such machines to control the population, which the Twonky soon demonstrates by walking into the room and altering his mind so that he no longer believes there to be a problem. As the now-fixed Trout attempts to leave, police storm into the house in response to a call made by the device seeking female companionship for West, followed by Treasury men tracking down the $5 bills manufactured by the device. When the law enforcement officers attempt to arrest West, though, the Twonky places all of them in a trance, and they leave without complaint.
Frustrated, West escapes the house and returns drunk, only to have the Twonky return him to sobriety with a ray. When his wife returns to see a visiting bill collector driven from their home by the machine, West decides to take action. Luring the device into his car, he attempts to crash it by a variety of means but is frustrated by the Twonky’s ability to control the vehicle. Spotting a vehicle parked alongside the road, West pulls over and abandons his car, hitching a ride from the other driver, an elderly Englishwoman. His relief at having escaped is soon negated by the woman’s erratic driving, and by the discovery that the Twonky was able to hide in the trunk. When the Twonky attempts to stop the woman’s reckless driving, it precipitates a crash that destroys the device for good.
