Draft:Thimble Theatre

Segar's Thimble Theatre debuted in the New York Journal on December 19, 1919. The paper's owner, William Randolph Hearst, also owned King Features Syndicate, which syndicated the strip. Thimble Theatre was intended as a replacement for Midget Movies by Ed Wheelan (Wheelan having recently resigned from King Features). While initially failing to attract a large audience, the strip nonetheless increasingly accumulated a modest following as the 1920s continued. At the end of its first decade, the strip resultantly appeared in over a dozen newspapers and had acquired a corresponding Sunday strip (which had debuted on January 25, 1925, within the Hearst-owned New York American paper).

Thimble Theatre's first main characters were the lanky, long-nosed slacker Harold Hamgravy (rapidly shortened to simply "Ham Gravy") and his scrappy, headstrong girlfriend Olive Oyl. In its earliest weeks, the strip featured the duo, alongside a rotating cast of primarily one-shot characters, acting out various stories and scenarios in a parodic theatrical style (hence the strip's name). As its first year progressed, however, numerous elements of this premise would be relinquished (including the recurring character "Willie Wormwood", introduced as a parody of melodrama villainy), soon rendering the strip a series of episodic comic anecdotes depicting the daily life and dysfunctional romantic exploits of Ham Gravy and Olive Oyl. It could be classified as a gag-a-day comic during this period.

In mid-1922, Segar began to increasingly engage in lengthier (often months-long) storylines; by the end of the following year, the strip had effectively changed fully into a comedy-adventure style focusing on Ham, Olive, and Olive's ambitious-but-myopic diminutive brother Castor Oyl, initially a minor character yet arguably the protagonist of the strip by 1925. Castor and Olive's parents Cole and Nana Oyl also made frequent appearances beginning in the mid-1920s. By the late 1920s, the strip had likewise acquired a number of notable characters beyond the sphere of Ham Gravy and the Oyl family, including Castor Oyl's wife Cylinda (to whom he was married from 1926 to 1928), her wealthy, misanthropic father Mr. Lotts and Castor's fighting cockerel Blizzard, all of whom had exited the strip by the close of 1928 (although Cylinda would eventually maritally reunite with Castor under R. K. Milholland's authorship almost a century later).

Introduction of Popeye

Popeye in his first appearance

Popeye first appeared in the strip on January 17, 1929, as a minor character. He was initially hired by Castor Oyl and Ham Gravy to crew a ship for a voyage to Dice Island, the location of a casino owned by the crooked gambler Fadewell. Castor intended to break the bank at the casino using the unbeatable good luck conferred by stroking the head feathers of Bernice the Whiffle Hen. Weeks later, on the trip back, Popeye was shot many times by Jack Snork, an undercover stooge of Fadewell's, but survived by rubbing Bernice's head. After the adventure's conclusion in June, Popeye left the strip, but, owing to reader reaction, he was brought back after an absence of only five weeks.

Ultimately, the Popeye character became so popular that he was given a larger role by the following year, and the strip was taken up by many more newspapers as a result. Initial strips presented Olive as being less than impressed with Popeye, but she eventually left Ham to become Popeye's girlfriend in March 1930, precipitating Ham's exit as a regular weeks later. Over the years, however, she has often displayed a fickle attitude towards the sailor. Initially, Castor Oyl continued to come up with get-rich-quick schemes and enlisted Popeye in his misadventures. By the end of 1931, however, he settled down as a detective and later on bought a ranch out west. Castor's appearances have resultantly become sparser over time. As Castor faded from the strip, J. Wellington Wimpy, a soft-spoken and eloquent yet cowardly hamburger-loving moocher who would "gladly pay you Tuesday for a hamburger today" was introduced into the Sunday strip, in which he became a fixture by late 1932. After first appearing in the daily strip in March 1933, Wimpy became a full-time major character alongside Popeye and Olive.

Thimble Theatre was renamed Thimble Theatre Starring Popeye starting February 4, 1931. It was eventually renamed simply Popeye, the name under which the strip continues to run.

Partial entry into the public domain

On January 1, 2009, 70 years since the death of his creator, Segar's comic strips (though not the various films, TV shows, theme music, and other media based on them) became public domain in most countries, but remained under copyright in the United States. Because Segar was an employee of King Features Syndicate when he created the Thimble Theatre strip, it is treated as a work for hire under U.S. copyright law. Works for hire are protected for 95 years from publication or 120 years from creation, whichever is shorter. On January 1, 2025, the Thimble Theatre strip that introduced Popeye entered the public domain. Certain elements of Popeye's character had already lapsed into public domain due to inconsistent copyright registrations and renewals on the strip and animated films; the first mention of Popeye eating spinach as a source of strength was in a 1931 strip in which the copyright was not renewed. However even after Popeye's debut strips entered the public domain, King Features still retains trademarks regarding Popeye's name and image. Unlike copyright, trademarks do not expire unless they cease to be used, and King Features has used the Popeye trademark continuously since registering it in 1931.
