The Long Death of the Seven-Minute Cartoon

October 14, 2026 · CartoonLedger

The golden-age register on this site runs from 1930 to 1969 and then stops. One thousand and two rows, and after September 1969, nothing, until revivals decades later that the ledger counts separately. The shorts did not run out of ideas, and they did not run out of audience; Bugs Bunny was more famous in 1969 than he had been in 1945. What they ran out of was money, and the money did not leave all at once. It was taken in three distinct blows over twenty-one years: a court ruling, a technology panic, and a box in the living room. This file is the autopsy, with dates.

The court ruling

For the first two decades of the ledger, the seven-minute cartoon had a captive customer. Theaters bought a studio's whole program, features and shorts bundled together, a practice called block booking, which meant the cartoons were effectively pre-sold before a frame was drawn. In 1948 the Supreme Court's Paramount antitrust ruling ended the bundle, and shorts suddenly had to be sold on their own. Theater owners, given the choice for the first time, were not inclined to pay much for seven minutes of rabbit. Rental income sagged while costs rose, and the squeeze is visible in how the cartoons themselves were made: production manager John Burton's era brought a five-week schedule per short under producer Edward Selzer, writers leaned harder on dialogue because talk is cheaper to animate than action, and Chuck Jones reportedly had crew time cards doctored to hide the extra weeks he spent on his specials. The famous late-period polish was produced inside a shrinking box. The cartoons were still profitable in the early 1950s, but the margin now had a clock on it.

The rehearsal

The first actual stoppage was a false alarm, and it is one of the strangest entries in the whole record. In June 1953 Warner shut the cartoon studio entirely, not over cartoons, but over 3-D: the studio feared the stereoscopic craze would become the standard and that 3-D cartoons would be ruinously expensive. The staff scattered, Jones to Disney among them. The craze collapsed within months, the studio reopened about five months later, and the whole episode left exactly one artifact in the ledger: Lumber Jack-Rabbit, released September 25, 1953, the only Warner cartoon ever produced in 3-D, a Bugs short that now plays flat and unremarkable on every screen it survives on. As a cartoon it is a footnote. As a precedent it was enormous: the studio had learned that the cartoon division could be switched off, and the industry had learned that nobody's walls fell down when it happened. The 1953 closure was the rehearsal for 1963.

The box in the living room

Television is usually blamed for killing the theatrical short, and the ledger agrees, but the mechanism was stranger than audiences simply staying home. Television revealed that the back catalog was worth more than the production line. On February 12, 1955, Warner sold television rights to 191 black-and-white cartoons to Guild Films through a subsidiary, with the Warner references scrubbed from the prints so theater owners would not notice their suppliers selling to the enemy. On June 11, 1956, the a.a.p. deal went further and sold the entire pre-August-1948 color library outright, everything through Haredevil Hare, the package whose strange afterlife this site has already traced through the defaced reissue prints and the Censored Eleven. And in the fall of 1960 The Bugs Bunny Show premiered on ABC, three old theatrical cartoons an episode in new wrappers. Every one of those transactions said the same thing to the accountants: the cartoons already in the vault earned money forever at no cost, while new ones cost more every year to sell into a market that no longer had to buy them. MGM had already read that memo and shut its cartoon studio in 1957. Warner held out longer than almost anyone, which is the only reason this register reaches 1969 at all.

The end of the line

The last act began with a personnel file. In 1962 Warner discovered that Chuck Jones had moonlighted on the script of the UPA feature Gay Purr-ee, a breach of his exclusive contract, and he was terminated that July, most of his unit following him out the door. Late that same year, at a board meeting in New York, David H. DePatie was told the studio would close; he spent the following months winding it down, and in May 1963 the doors shut. What followed was a long epilogue wearing the famous names. DePatie and Friz Freleng leased the old building, and from 1964 to 1967 their company produced new Looney Tunes and Merrie Melodies under contract, mostly Daffy Duck pursuing Speedy Gonzales, while a separate outfit turned out budget Road Runners. The last theatrical Bugs Bunny cartoon of the original run, False Hare, was released July 18, 1964; the character who carried the studio went quietly, mid-slate, with no ceremony whatsoever. In 1967 Warner, now Warner Bros.-Seven Arts, brought production back in-house and tried new stars on new budgets: Cool Cat, Merlin the Magic Mouse. Robert McKimson, who had directed Bugs since the 1940s, came back to direct a beatnik tiger.

A remake title walks it home

The final entry in the original run is Injun Trouble, released September 20, 1969, a Cool Cat cartoon directed by McKimson, and the ledger savors the detail that it is a remake title: the name had already been used by a 1938 Porky Pig short, which is why both rows exist under the remakes-count-twice rule this site runs on. The series that opened in 1930 with a singing frolic closed thirty-nine years later with a borrowed name, and the last gag of the last cartoon has Cool Cat cutting a hole in the backdrop and telling the audience to cool it now. Three weeks later, on October 10, 1969, Kinney National acquired the company and ended all short-subject production. Nobody drew a farewell. The production line simply did not restart, the way it had after 1953, and this time there was no craze to blame and no reopening five months out.

What the end date teaches

The doctrine, for reading the whole register. The 1969 cutoff that defines the checklist is not an artistic judgment, and it is not when the characters died; they went on to decades of television, compilation features and revivals that the ledger counts under their own rules. It is an economics date, the moment the last studio still manufacturing seven-minute theatrical cartoons stopped, twelve years after MGM, having survived a court ruling that unbundled its product, a 3-D panic that shut it once, and a television market that made its own vault its competitor. The register's shape records all three blows: the lush 1940s rows, the tightening 1950s, the thin contract-era 1960s. And the afterlife proves the accountants right in the bleakest way, because the library they stopped adding to in 1969 has been earning continuously ever since, through syndication, the Golden Collection window, and every disc this site tracks. The cartoons were never a failing product. They were a product whose old units outearned its new ones, and the ledger's end date is simply the day the company believed its own arithmetic.
