The first acquisition is the All-American line. For a period of time (about two years), their books were still getting a lot of play, but by 1950, they were all dying off. Even though Wonder Woman stuck around, she still lost her place in SENSATION COMICS, as well as ALL-STAR COMICS (plus the earlier loss of COMIC CAVALCADE which converted to the funny animals format). Most of the All-American characters fell into limbo before finally being revived on Earth-Two in the 1960s.
Quality Comics is an odd one. After buying up a lot of properties, they only continued G.I. COMBAT, HEART THROBS and BLACKHAWK. At first glance, you'd think they would have continued PLASTIC MAN but the later Quality issues were mostly just reprints of earlier comics. Jack Cole had left for other things and would die in 1958, so there probably was no talent they could hire from Quality to maintain the quality. Even when they did revive PLASTIC MAN in 1967 it only lasted for ten issues--and then in 1976 it had another ten issues. For many people the genius of Plastic Man is Jack Cole--this would be like reviving the Spirit without Will Eisner.
While most of the other Quality characters were brought back in the 1973 Earth-X story, when the FREEDOM FIGHTERS got their own series in 1976 they had left for Earth-One. And in ALL-STAR SQUADRON, Roy Thomas established that all these Quality characters were native to Earth-Two and only left for Earth-X because it needed them to fight the Ratzis over there. So you've got Quality characters as immigrants travelling between Earths. Meanwhile, Kid Eternity (owing to the similarity to Captan Marvel, Jr.) was established on Earth-S! The perception of Earth-X as the Quality Earth doesn't hold up, since these characters were spread out over many Earths and some of them had become established as part of Earth-One before there was an Earth-X. Mind you, as an Elseworld series, Earth-X would have been a good concept to explore.
Earth-S! was hampered by the fact that the characters were only borrowed from Fawcett. They got permission to use the Marvels and then some of the other Fawcett heroes (Shazam's Squadron of Justice), but not owning them probably is why they were never amalgamated into Earth-One before the Crisis. Once Captain Marvel and his family were bought outright from Fawcett, there was more incentive to bring them into the mainstream. But after the 1970s, the Fawcett characters have struggled to get attention and often been ignored.
The Charlton Earth was never a part of continuity until the Crisis and they were only brought in to destroy them, so they could be brought back as either THE WATCHMEN or as rebooted versions of the originals. The big period for Charlton usage was right after Crisis in the late 1980s and early 1990s. But like every other acquisition, the publisher seemed to lose interest in them after that. It's been an uphill battle for the Charltons to get back on top.
And it's the same with Archie !mpact Red Circle, Milestone, Wildstorm, Thunder Agents et al. When they first get the property, they make an effort, but then they start to lose interest and can't be bothered.
