KIII
The station relaunched on May 4, 1964, as KIII,[19] a full ABC affiliate.[20]
South Texas Telecasting, which had by this time added Clinton D. McKinnon as its major stockholder and executive vice president but still retained most of its original board of directors, later evolved into McKinnon Broadcasting, who remained the station's owners until 2010.
In 1969, KIII started a satellite in Victoria, Texas, KXIX (channel 19), to bring ABC programming to that area.[21] In 1976, KXIX was sold to local ownership. It now operates as Fox affiliate KVCT.
On April 29, 2010, it was announced that KIII would be acquired by London Broadcasting Company.[22] The sale was closed on August 31.[23] On September 18, 2011, KIII began broadcasting newscasts in high definition.
On May 14, 2014, the Gannett Company announced that it would acquire KIII and five other LBC stations for $215 million. Gannett's CEO Gracia Martore touted that the acquisition would give the company a presence in several fast-growing markets, and opportunities for local advertisers to leverage its digital marketing platform.[24] The company also owns fellow Texas ABC affiliates WFAA and KVUE, which it had acquired in its purchase of Belo Corporation. The sale was completed on July 8.[25] 13 months later, on June 29, 2015, the Gannett Company split in two, with one side specializing in print media and the other side specializing in broadcast and digital media. KIII was retained by the latter company, named Tegna.[26]
Nexstar Media Group acquired Tegna in a deal announced in August 2025[27] and completed on March 19, 2026.[28]
