Both series have decades of history and have been intertwined in the public imagination for some time, not least of all because the driving creative force behind both was manga artist Shotaro Ishinomori and both were produced by the same production company, Toei Company; however, they did not air together until 2000 with Kamen Rider Kuuga and Kyuukyuu Sentai GoGoFive (which was quickly replaced by Mirai Sentai Timeranger 2 weeks later), though at the time they were not acknowledged together.

Over the years the hour began including henshin (transforming) hero programs, one of the first being Warrior of Love, Rainbowman (愛の戦士レインボーマン, Ai no Senshi Reinbōman).

The Super Hero Time block is part of the larger Nichi Asa Kids Time (ニチアサキッズタイム, Nichi Asa Kizzu Taimu, "Sunday Morning Kids Time") block, which begins at 8:30 JST with the airing of an ABC Television-produced shōjo anime animated by Toei Animation (currently the Pretty Cure series) and ends at 10:00 JST after the airing of the Super Sentai series.

In 2020, production of new episodes for both Kamen Rider Zero-One and Mashin Sentai Kiramager was temporarily halted due to the impact of COVID-19 pandemic in Japan, including one of Kiramagers cast members being infected, with special episodes containing old, unreleased footage being aired in the block until June, when production resumed, following a series of health and safety compliances.

This block has been shown on TV Asahi (Tokyo), Mētele (Nagoya), ABC (Osaka) and all other stations of the All-Nippon News Network (Nationwide) via satellite.
