Sure, those apply. Masterpiece Theatre was long hosted by Alastair Cooke and Mystery! was once hosted by Vincent Price.
I've actually discovered a few more on a DVD set I have entitled "The Golden Age of TV Drama: 16 Rare and Remarkable Dramas from 1951-1960!" from Passport Video...

DuPont Theatre (1952-1957): Also known as
Calvacade of America and
DuPont Calvacade Theater was an anthology series sponsored by the DuPont Company. According to Wikipedia, it "documented historical events using stories of individual courage, initiative and achievement, often with feel-good dramatizations of the human spirit's triumph against all odds. This was consistent with DuPont's overall conservative philosophy and legacy as an American company dating back to 1802. The company's motto, "Maker of better things for better living through chemistry," was read at the beginning of each program, and the dramas emphasized humanitarian progress, particularly improvements in the lives of women, often through technological innovation." Many of the stories were crime-based too.

The United States Steel Hour (1953-1963): Classic anthology series sponsored by the United States Steel Corporation adapted hundreds of plays in live TV dramas. Like the Dupont show, this started as well as a radio series that later moved to TV. They'd also do live musical adaptations of Huck Finn and Tom Sawyer.
"The television version aired from 1953 to 1955 on ABC, and from 1955 to 1963 on CBS. Like its radio predecessor, it was a live dramatic anthology series. During its first season on television, the program alternated bi-weekly with The Motorola Television Hour.
By 1963, the year it went off the air, it was the last surviving live anthology series from the Golden Age of Television. It was still on the air during President John F. Kennedy's famous April 11, 1962 confrontation with steel companies over the hefty raising of their prices. The show featured a range of television acting talent, as its episodes explored a wide variety of contemporary social issues, from the mundane to the controversial." - Wikipedia

"The series featured original dramas by noted writers, although sometimes comedies were shown. Its guidelines specifically called for the avoidance of violence. Originally a half-hour production, in 1955 the show expanded to an hour and began to emphasize dramatized versions of real-life contemporary events (including the sinking of the SS Andrea Doria and a documentary on the history of Communism in the Soviet Union. Upon moving to CBS, the show emphasized several Cold War topics, including espionage, Radio Free Europe and escapes from East Germany.
Rod Serling wrote two episodes of the program. George Lowther was the producer for 62 episodes and wrote one." - Wikipedia
Actually I suspect there's even more from the 50s yet and likely some more British anthologies that haven't been named yet...
