Earth magazine reflected the vibrant cultural landscape of late 1960s/early 1970s, typical of the era's underground press.

Notable features included events like the 1970 Isle of Wight Festival, showcasing performers such as Roger Daltrey, Joan Baez, Jimi Hendrix, Miles Davis, Donovan, and John Sebastian; alongside striking images of naked audience members.

Earth made news in March 1972 by publishing a story claiming that in the summer of 1968 the U.S. Army had tested nerve gas in Cambodia.

In 1974 it launched "Earth Starship," a five-day-a-week service offering subscriber radio stations coverage of contemporary music, film, and other entertainment facets.

Meanwhile, in 1972 Jonathan Newhall,[9][10] another former Earth staffer,[5] co-founded with John Farley[11] Zodiac News Service,[12] headquartered on Howard Street.

In 1977, Zodiac staffers Marlene Edmunds and Anne Millner[13] formed Her Say, a feminist alternative news service, along with Shelley Buck.
