WIAC (740 AM) is a radio station broadcasting a News Talk Information and Spanish Variety format. Licensed to San Juan, Puerto Rico, it serves the Puerto Rico area. The station is currently owned by Bestov Broadcast Group. History Puerto Rico's first advertising agency, the West Indies Advertising Company (WIAC), was founded in San Juan in 1933, by the Abarca family, which also owned a successful structural steel company. By 1942 the advertisement agency's management founded WIAC at 580 kHz, with Félix Muñiz, the brother of Tomás Muñiz (and uncle of Tommy Muñiz, as its administrator. Due to the untimely death of Félix, Tomás became the station's administrator soon after. WIAC operated on 580 kHz in San Juan from 1942 to 1947, a frequency later occupied by WKAQ. WIAC officially began operations in March 1947, moving to 740 AM, replacing WIBS in Santurce. During the 1950s and 1970s, WIAC was the only radio station broadcasting weather forecasts every 10 minutes and public affairs programming. In 1961, Bestov Broadcasting, Inc. (a radio company owned by Alan Mejía and his brother, Luis Mejía) acquired the station, along with WIAC-FM 102.5 FM (formerly Sistema 102), which began operations that same year. In 1962, Bestov acquired WISA 1390 AM in Isabela serving the western and north area, and it is owned by Mejia's subsidiary, Isabela Broadcasting, Inc., this serving as a satellite of WIAC. In 1982, WIAC changed its news programming, with the branding of "WIAC NotiReloj". In 1998, WIAC NotiReloj became Cadena Radio Puerto Rico, with a News/Talk format. In 1999, Bestov Broadcast Group acquired WEKO 930 (now WYAC) in Cabo Rojo from David Ortiz Cintron, a radio entrepreneur from Cabo Rojo, which becomes a repeater of WIAC. Bestov also acquired WTIL 1300 AM in Mayaguez and would become the repeater of WEKO until 2003. In 2009, WIAC reached an agreement with Boricua-JE Broadcasting, inc., the station's licensee to change to Boricua 740. On February 1, 2012 WIAC's owner Bestov Broadcast Group joined in an alliance with Noti-Luz, buying from Empower Media Group, forming Puerto Rico's only AM and FM news and talk station. The Noti-Luz Network consisted of WGIT 1660 AM in Canóvanas, WIAC 740 AM in San Juan/Ponce, WYAC 930 AM in Cabo Rojo/Mayagüez, WISA 1390 AM in Isabela, WJDZ 90.1 FM in Pastillo, WNNV 91.7 FM in San Germán, WEKO 1580 AM in Morovis and WXRF 1590 AM in Guayama.
