The segments were broadcast in the United States on the CBS television network from 1971 until 1986, between Saturday morning animated cartoon programs, alongside features like Schoolhouse Rock!
The "micro-series" (as it would be labeled today) had its genesis in a series of animated interstitials produced by CBS and Hanna-Barbera Productions called In the Know, featuring Josie and the Pussycats narrating educational news segments tailored for children.
Video clips of national or world events and special-interest stories were shown with voice-over narration specifically written with children in mind.

The series was briefly revived as part of CBS's all-"educational/informational" Saturday morning lineup during the 1997–1998 season, but without the involvement of original narrators Glenn and Shepard.
