The newspaper diversified during the mid-20th century, founding and owning Sharon radio station WPIC from 1938 to 1959; purchasing four eastern Mercer County weeklies in 1965, eventually merging them into the now-twice-weekly Allied News in Grove City; and founding a weekly newspaper, Hubbard Press, in Hubbard, Ohio in 1997.
On Feb. 23, 1970, The Herald dropped "Sharon" from its nameplate to reflect its countywide audience.
