AFTRA members and another 32 of NABET joined the action. The strike lasted more than two years and featured a secondary boycott of the station led by the unions, leading to the loss of several advertising contracts; at various times, both parties were found to be guilty of unfair labor practices. In a final ruling at the end of 1964, the National Labor Relations Board found that unions were allowed to engaged in publicity other than picketing and thus that their actions were protected. This was affirmed in 1966. Corinthian purchased a studio site at 400 Broadway in downtown Sacramento to relocate KXTV in 1965; the 7th Avenue site was in the path of the proposed Interstate 5 freeway. The station moved on January 15, 1968, and the property was then sold to the state of California. In 1971, Corinthian merged with Dun & Bradstreet, a publisher of trade and technical publications and directories. Belo ownership and affiliation switch to ABC The Corinthian group was sold to the A.

The deal allowed Belo to enter the Texas state capital, a market of significant strategic importance to the Dallas-based company, and gave it a presence in two thirds of Texas TV households. The deal closed in July, and the general manager of KVUE moved to Sacramento to run KXTV. In 2000, the station constructed the News10 Weather Tower, which was finished by October but first lit on August 24, 2001, owing to the energy crisis in the state at the time. In addition to providing microwave transmission capabilities for the station—which had to trim trees at homes in the Land Park neighborhood prior to its installation—it originally functioned as a weather beacon with
