Frank Batten, Slover's nephew, took over the company in 1955, and changed its name to Norfolk-Portsmouth Newspapers Inc. in 1957 (reflecting the merger of the Norfolk Ledger-Dispatch and Portsmouth Star), then to Landmark Communications in 1967.

The businesses owned by Dominion Enterprises include DominionDMS, Activator, Dealer Specialties, Cross-Sell, DataOne Software, Prime Street, Franchise Ventures, DX1, ZiiDMS, and Travel Media Group.

One of Landmark Communications's holdings was TeleCable Corporation, a cable television service that began in a small Virginia town in the late 1950s.

Landmark obtained franchise licenses to operate in about two dozen cities throughout the eastern half of the U.S., including Overland Park, Kansas; Plano & Arlington, Texas; Bloomington, Illinois; Racine, Wisconsin; Springfield, Missouri; Wytheville & Princeton, Virginia; Selma, Alabama, and other cities.

Customers complained to TeleCable of Overland Park that they missed the 7 p.m. movie start due to late working hours, dinner, or children's activities.

Landmark's predecessor, Norfolk Newspapers, entered broadcasting in 1930, when it bought Virginia's oldest radio station, WTAR.

However, U.S. Federal Communications Commission (FCC) cross-ownership rules forced Landmark to sell off WFMY in 1976 and WTAR-TV in 1981.

Landmark briefly owned WDBJ-TV in Roanoke, Virginia, but was forced to sell it immediately due to FCC restrictions.

On January 23, 2010, CB divested its Richmond Business Unit, NET Telcos, to Cavalier Telephone, a full-service provider of telecommunications solutions.

[9] Two separate investment banks, JPMorgan Chase and Lehman Brothers, were hired to help with the sale of The Weather Channel and the newspapers.

[10] On July 14 of that year, it was announced that WTVF in Nashville, Tennessee would be sold to Bonten Media Group,[11] but that sale did not close.

[12] In October 2008, the company suspended further sales of its properties, citing the ongoing credit crisis, with the exception of The Virginian-Pilot newspaper.

[15] CBS affiliate KLAS-TV, based in Las Vegas, Nevada, was acquired by Landmark in 1978 from a trust left by Howard Hughes upon his death.

[22] In April 2021, Landmark announced the sale of Homes.com, a unit of its Dominion Enterprises subsidiary, to CoStar Group Inc. for $156 million.
