"Azteca Trece" and "Azteca Siete" – which maintained a lineup of programs, including telenovelas and other serialized dramas with socially relevant themes, that helped it quickly grow to maintain a 36% ratings share during prime time against competition from the longer established and dominant Televisa networks. Azteca founder Ricardo Salinas Pliego had made previous attempts at entering into U.S. television during the late 1990s; it made a failed attempt to acquire an equity interest in Telemundo in 1998, but eventually agreed to a short-lived co-production and program distribution agreement with the network. In 1999, the network also tried to negotiate a joint venture with the upstart Hispanic Television Network; CEO Marco Camacho had also rejected an exclusive content agreement between HTVN and Azteca due to questions over the appeal of the latter's programming to Latino Americans, although a spokesman for TV Azteca stated that the network pulled out due to a lack of confidence in HTVN's overall national distribution. On December 21, 2000, the Pappas-Azteca joint venture received approval from the Federal Communications Commission (FCC) to launch a full-power television station in Los Angeles, California (where it would base its headquarters), KIDN-TV (channel 54) – which was later reassigned the call letters KAZA-TV prior to its launch. The network, through both companies, planned to acquire stations in twelve markets to serve as Azteca América's charter stations. The plans for the network were eventually scaled down, as a slowdown of the world economy hurt Azteca América's plans to secure financing to purchase stations in Dallas (where Pappas-Azteca attempted to acquire independent station KXTX, which was bought by Telemundo instead for $65 million) and El Paso, Texas. Also playing a factor was the December 2000 purchase of USA Broadcasting's thirteen major-market television stations by Univision Communications, which prevented the network from initially obtaining charter stations in major markets such as New York City and Miami; the Pappas-Azteca venture also called off a $37.5 million deal to purchase WSAH (now WZME) in Bridgeport, Connecticut from Shop at Home, Inc. (which would have given Azteca América a station in the New York City market) in November 2000. KAZA-TV signed on the air as Azteca América's lone station on July 28, 2001, as part of a phased rollout cited by lower viewership during the summer months; Pappas also announced that it would switch some of its existing stations to Azteca América and attempt to purchase
