However, after three years with no new Taz cartoons, Jack Warner asked Edward Selzer what happened to Taz. It is believed that Edward Selzer changed his mind only upon being informed by Jack Warner that Taz was a massive hit with audiences. He then saved Taz's career when he told Selzer that he had received "boxes and boxes" of letters from people who loved the Tasmanian Devil, and wanted to see more of him, forcing Robert McKimson to create four more Taz cartoons, until Warner Bros. closed down its cartoon division in 1964. Taz became much more popular later on through merchandising and even getting his on show in the form of *Taz-Mania*. It may come to as a surprise to some fans that Taz only appeared in 5 of the Golden Age-era theatrical cartoons.

## Comics
* **Krazy Kat** evolved from an earlier comic strip of series artist George Herriman's, *The Dingbat Family*, which started in 1910 and was later renamed *The Family Upstairs*. This comic chronicled the Dingbats' attempts to avoid the mischief of the mysterious unseen family living in the apartment above theirs and to unmask that family. Herriman would complete the cartoons about the Dingbats, and finding himself with time left over in his 8-hour work day, filled the bottom of the strip with slapstick drawings of the upstairs family's mouse preying upon the Dingbats' cat. This "basement strip" grew into something much larger than the original cartoon. It became a daily comic strip with a title (running vertically down the side of the page) on October 28, 1913 and a black and white full-page Sunday cartoon on April 23, 1916. Due to the objections of editors, who considered it unsuitable for the comics sections, *Krazy Kat* originally appeared in the Hearst papers' art and drama sections. Hearst himself, however, enjoyed the strip so much that he gave Herriman a lifetime contract and guaranteed the cartoonist complete creative freedom.
* **Nero** from *The Adventures of Nero* by Marc Sleen was originally introduced as a side character in the series *De Avonturen van Detective Van Zwam*, where Detective Van Zwam was the main protagonist. From the first Van Zwam story on, *Het Geheim van Matsuoka* ("Matsuoka's Secret") (1947) readers reacted more enthusiastically to the dumb, lazy, vain and stubborn character Nero than the more noble and clever Van Zwam. So, from "De Hoed van Geeraard de Duivel" ("The Hat Of Gerard the Devil" (1950)) onward the series was named after Nero instead.
* **Popeye** first appeared 10 years into the run of *Thimble Theatre*, a comic strip started in 1919 by E.C. "Elzie" Segar for the King Features Syndicate. The strip initially focused on Olive Oyl, her family, and her boyfriend Ham Gravy. Segar introduced Popeye as a sailor hired by Olive's brother Castor to facilitate a single adventure. When the sailor character disappeared from the strip afterwards, Popeye fans demanded his return, and the series later became *Thimble Theater, Starring Popeye*. Due to his popularity, Popeye finally received toys, feature films, video games, books and even a series of theatrical cartoon shorts.
* The **Smurfs** were originally supporting characters in Peyo's comic series *Johan and Peewit* in 1958. The popularity of the little blue men led to them getting their own series a year later, which was subsequently followed by massive merchandising, a television series and various other productions.
* **Smurfette** first appeared in 1966. Due to her massive popularity, Smurfette finally became an global icon, becoming the true main protagonist of the franchise. As Smurfette's popularity increased, this era led to her becoming the official mascot of Peyo Creations.
