The Ina Ray Hutton Show was a TV show starring prominent female jazz bandleader Ina Ray Hutton and her all-female orchestra. From 1951 to 1955, the show was a regional television show on the Paramount Television Network flagship station KTLA, and had a brief network run on PTN in 1956.
The show was a regional television show for more than 10 years.
It's definitely incorrect because it was only a regional show from 1951 to 1955. I think it was difficult for the system because verifying the statement requires more than one calculation/comparison, which is complex.
