It is the namesake of the Daily Herald Media Group, and through it is the leading subsidiary of Paddock Publications.

[1] The Daily Herald serves Cook, DuPage, Kane, Lake, and McHenry counties and has a coverage area of about 1,300 square miles (3,400 km2).

The paper grew along with northwestern Cook County after World War II, as four-lane highways and the expansion of the Chicago & North Western's commuter rail line in the northwest suburbs (now the Union Pacific/Northwest Line) turned it into a suburban area.

This move came almost out of necessity; Field Communications, publisher of the Chicago Sun-Times, had introduced its "Daily" papers for the northern suburbs in 1966.

A brutal one-year circulation war ensued, ending in 1970 when Field pulled out of the area.

That year, the paper dropped Arlington Heights from its masthead after merging with its sister publications and expanding into Lake County.
