And for those who prefer reading to listening, I did not have time for a proper transcript, but here is a short summary of each video. But you should look at them! There is more detail in there than I listed.
Part One (1920-1942)
Sentinel Comics was founded in St. Louis in the 1920s during Prohibition by the Cataneo Mob family. Dominic Cateneo, the head of the family, welcomed Roberto Tucci into the family when he married Cateneo’s daughter in 1936; Bob was placed in charge of the newstands to keep him out of trouble, and ended up in charge of a pulp magazine, which he turned into a comic publisher. So suddenly the mob was in charge of a comics company!
Early Sentinel Comics titles were based on the publishers’ former pulp magazines, and succeeded through a mixture of modest success and money laundering. While expanding into crime stories, one writer submitted a superhero, “Legacy”. Legacy was not the first superhero - apparently GR Comics had opened the door with “Centurion”, and another compnay had “Optimus”. But Legacy was different, being a soldier and not a vigilante, with no formal secret identity (although his civilian identity half stood in.) Justice Comics became a huge success, and the Cataneos helped get a Legacy serial off the ground, leading to even more popularity (and a villain, Admiral Zhan, that I’ve never heard of before!) There is some absolutely amazing fake footage from this serial if you want to check it out.
Part Two (1942-1954)
During World War II, Sentinel Comics lost a bunch of people to drafting, including the creator of Legacy, Harvey Brooks. While at war, Brooks served with a Maori detachment from New Zealand, leading to the creation of Haka post-war. Post-war, superhero title sales were falling off, and the new titles were true crime and horror, leading to the creation of Criminal Element, Shudder, Mystery Comics, Arcane Tales, and Tome of the Bizarre.
Then Senator F. Morton Selinker started a campaign against comic books and other objectionable “children’s materials”. After a series of open feuds between Selinker and Tucci, committees were formed in the mid-50s, culminating in Bob Tucci being called to testify in 1954. At that meeting, Selinker confronted Tucci with the knowledge that Sentinel Comics was literally owned by the mob.
Part Three (1947-1968)
This one actually starts in 1954 despite the title screen. After the disastrous 1954 hearings, the Cataneos sold the company to avoid government scrutiny. The new buyer, “Sir” Douglas St. John-Dewberry, was a publisher and UFO enthusiast who pretended to be British and a lord, and who appointed a veteran editor to oversee things. The new editor ended the crime and horror lines, turning Mystery Comics into the Wraith’s playground and turning the horror lines into superhero stories. The Wraith in particular proved amazingly popular, leading to a 1965 TV show.
These timelines don’t line up with the current listed first appearances of several characters; the video says that Haka, Scholar, and Black Fist are all post-sale creations, as was the creation of the Freedom Four comic. That doesn’t quite work timeline-wise; those heroes were introduced between 1948 and 1952, and Freedom Four started in 1950. History of Sentinel Comics will likely address this.
Part Four (1968-1989)
During the 60s and 70s, Sentinel Comics grew into one of the top four comics publishers. Popular new characters like Nightmist, Ra, Tempest, Captain Cosmic, Argent Adept, and Fanatic became popular stalwarts. (Once again, there is a minor timeline issue here, as Ra was a Golden Age hero.) In the early 1980s, Tome of the Bizarre began doing horror again, and popular writer Guy Hampton (who is definitely not Alan Moore) invented Man-Grove as a dark and gritty title. Hampton ultimately created a religion based around his belief in his magical powers and a badger puppet that he declared was his god. Hampton ultimately left Sentinel Comics after threatening to blow up his editor.
In 1985, Sentinel Comics was sold to a foreign industrial company who then sold it for quite a bit more in 1989 to billionaire industrialist Owen Timothy, who planned to take it public in the early 1990s.
Part Five (1990-2019)
In the early 90s, Sentinel Comics was in a collector’s boom. They did variant covers, crossovers, and created a number of “hot characters with guns”, including the notoriously unpopular hero Sk8Blayd. Ultimately, the company set up a poll on whether he would live or die; he lost the vote and died in the pages of Rook City Renegades.
Another note! Sk8 has been since clarified to have been created in 1986 and died in 1991 in Rook City Renegades #100, pushing this fictional event much closer to the real event it’s based on, and removing Sk8Blayd entirely from the early 90s boom that he was meta-fictionally created to be a part of. Ironic.
In the mid-90s, the market began to struggle, and Sentinel Comics declared bankruptcy in 1996. In the aftermath, investors formed Greater Than Industries, led by Christopher Badell and Adam Rebattaro (lolol), creators of some of the company’s recent popular titles, and took over Sentinel Comics, pulling it out of financial ruin over the course of several years. Sentinel Comics recovered and developed animated TV and movies, plus merchandising opportunities. This culminated in the grand company-wide OblivAeon storyline, which finally pushed Sentinel Comics to the number one company in the world.
