The Federal Communications Commission (FCC) began tightening its ownership restrictions in the 1970s, eventually barring common ownership of newspapers and broadcasting outlets. Landmark was able to get grandfathered protection for its flagship Hampton Roads cluster. However, in 1981, it opted to sell channel 3 to Knight-Ridder, who changed the station's calls to WTKR on March 4. The new calls not only reflected the new ownership (FCC rules prohibited TV and radio stations in the same market, but with different ownership from sharing the same callsigns then, hence the modification), but also sounded similar to the old ones. Knight-Ridder sold WTKR and sister station WPRI-TV in Providence, Rhode Island to Narragansett Television in 1989. Narragansett sold WTKR to The New York Times Company in 1995.
