In 1948, Don Angel Ramos in San Juan, Puerto Rico had decided that his brand new television station, Channel 2, needed an experienced and unique voice talent.
[1] When the word was given to go ahead and launch Channel 2, Evelio suggested to introduce the station as Telenoticias del mundo and Ramos agreed.
[citation needed] In 1961, after the birth of his son Evelio Jr., Otero moved to the brand new Channel 4 television station and became the first anchor at WAPA-TV.
On 31 December 1972, hall of fame baseball player, Roberto Clemente, visited Otero after appearing at a local game show on New Year's Eve requesting help for the suffering caused by the devastating earthquake in Managua, Nicaragua.
In 1980, Otero moved to Maryland, where he was hired as a senior editor for the (Voz de las Américas), Voice of America in Spanish.
