In its beginnings, "Noticentro 4" ran for only fifteen minutes in the afternoon, with a half-hour edition at 10:00 p.m.; there was also a weekend edition. Gradually, the program's running time was increased to a full hour. After Otero's departure, New York City-born William "Bill" Pérez became WAPA's news director (Torres held the post for a while, but eventually asked to serve only as a news anchor). In the late 1970s, Enrique Cruz, Luz Nereida Vélez, Sylvia Gómez, Luis Rigual, Cyd Marie Fleming, José Esteves, Luis Francisco Ojeda and others joined the news department.
