History
The station launched on July 16, 1953, under the call sign KROC-TV, making it the first station in Southern Minnesota and third in the state after KSTP-TV and WTCN-TV in the Twin Cities. It was owned by the Gentling family and their Southern Minnesota Broadcasting Company, and was a sister to KROC radio (1340 AM). The station's original studios and transmitter were located on Hennessey Hill, two miles (3.2 km) west of Rochester. The station carried programming from all four commercial networks of the 1950s: ABC, CBS, and DuMont but was a primary NBC affiliate. The station was launched by G. David Gentling, son of family patriarch Gregory P. Gentling. In November 1966, the station moved to a new building on First Avenue Southwest in Downtown Rochester.

Why this record matters
The phrase “nBC/CW affiliate in Rochester, Minnesota” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.
Named sources, stable identifiers and responsible institutions provide the strongest route from overview to verifiable evidence. The source revision retrieved here is dated Jul 15, 2026. The linked authority identifier is Q6339171. 2 of 2 selected statements include explicit references; 1 carry qualifiers and 0 use preferred rank. The first chronological checks are 1953, 1340 and 1966.
A concise general-reference account can conceal disagreements about scope, terminology or the weight assigned to individual sources. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
