Telemundo's effort faced an initial setback when Mexico's leading broadcaster, Televisa, purchased production company Capitalvision, which had been producing the telenovelas in conjunction with the network.
On April 14, 1983, Ramos sold WKAQ-TV to John Blair & Co.
In 1984, the owners of WNJU (channel 47) in Linden, New Jersey (serving the New York City area) and KSTS (channel 48) in San Jose, California formed Net Span, the second Spanish-language television network in the continental United States (behind the longer-established Spanish International Network, the forerunner to Univision).
These stations joined KVEA (channel 52) in Los Angeles, run by its general manager and part-owner Joe Wallach, in 1985.
The following year, KVEA's part-owner, Reliance Group Holdings, acquired the Telemundo brand when it purchased John Blair & Co., which also owned WSCV (channel 51) in Fort Lauderdale–Miami-West Palm Beach in addition to WKAQ-TV. In 1987, Reliance Capital Group executives Saul Steinberg and Henry Silverman merged all these stations into the Telemundo Group.
During the 1970s and 1980s, WKAQ-TV, then branded as "Telemundo Canal 2" ("Telemundo Channel 2"), had become a major producer of telenovelas.
