WAPA-TV is an independent television station located in San Juan, Puerto Rico transmitting over digital channel 27, virtual channel 4. The station is owned by InterMedia Partners and is branded as WAPA Television.

WAPA-TV has two full-power satellite stations: WTIN-TV, channel 4.1 in Ponce and WNJX-TV, channel 4.1 in Mayagüez. Both stations are also owned by InterMedia Partners.

WAPA-TV was the second television station to be licensed to Puerto Rico and began broadcasting on May 1, 1954. Its call letters are a partial abbreviation of the station's original owners, the now-defunct Asociación de Productores de Azúcar, or Puerto Rico Sugar Grower's Association. During its earliest years, the station was affiliated with NBC, ABC, DuMont, and the CMQ Television Network.

The station was the first to transition to color unceremoniously in 1966 on NTSC, followed by WKAQ-TV in 1968. Popularly known in Puerto Rico by its assigned channel number, Canal Cuatro, the station was also known by its animated cartoon mascot during the 1970s and 1980s, a bongo-playing cat (known commonly as el gato de WAPA in Spanish) and therefore its rhyming slogan is, Por el cuatro como el gato (colloquially "on four like the cat"), which rhymes in Spanish. Similarly, another TV spot used the phrase, Hasta el gato, te-ve el cuatro and the cat itself was alternately known as el Gato de Cuatro.

José Feliciano (born September 10, 1945) is a Puerto Rican singer, virtuoso guitarist and composer known for many international hits including the 1970 Christmas single "Feliz Navidad".

Feliciano was born in Lares, Puerto Rico, on September 10, 1945. Left permanently blind at birth as a result of congenital glaucoma, Feliciano was first exposed to music at age three and would play on a tin cracker can while accompanying his uncle playing the Cuatro. When he was five, his family moved to Spanish Harlem, New York City, and at age nine, he played the Teatro Puerto Rico in the Bronx. He started his musical life playing the accordion until his father and family friend, Benjamin Borges, gave him his first guitar in a brown paper bag. He played every chance he had by himself in his room for up to 14 hours a day listening to 1950s rock'n'roll records, classical guitarists such as Andrés Segovia, and jazz players such as Wes Montgomery. He later had classical lessons with Harold Morris, who earlier had been a student of Segovia.

Luis Francisco Ojeda (June 16, 1941) is a well known Puerto Rican television, radio reporter and host, noted for his aggressive, uncompromising questioning and commenting style.

Ojeda was born in Jayuya. He moved to Ponce when he was still a youngster. While studying in high school, he got his first opportunity to talk live in a daily show, becoming a newscaster for Ponce's WPAB radio station.

Ojeda signed a contract with WAPA in 1960, and moved to San Juan. He worked at WAPA as newscaster (and occasional disc jockey) until 1968, moving on that year to work for rival WKAQ-Radio Reloj. While there, he had to cover the historic riots at the University of Puerto Rico at Rio Piedras in 1971. In one of the incidents covered by Ojeda a shooting ensued, and Ojeda, in the middle of the shootout, rescued a police lieutenant who had been shot. Despite his efforts, the police officer died from his gunshot wounds in the back of the remote unit truck while Ojeda was broadcasting his and his driver's frantic rush to the nearest emergency room live.

Guillermo José Torres (born 1944) is a Puerto Rican television reporter and news anchorman^{[citation needed]}.

José ("Chegüi") Torres (May 3, 1936 – January 19, 2009), was a Puerto Rican professional boxer. As an amateur boxer, he won a silver medal in the junior middleweight at the 1956 Olympic Games in Melbourne. In 1965, he defeated Willie Pastrano to win the WBC and WBA light heavyweight championships. In 1997, he was inducted into the International Boxing Hall of Fame.

Born in the city of Ponce, Puerto Rico, Torres began boxing when he joined the U.S. Army as a teenager (he was 18 years old). His only amateur titles had come in Army and Inter-Service championships, several of which he had won. Torres was still in the Army when he won the Silver Medal in the light middleweight division at the 1956 Melbourne Olympic Games, where he lost to László Papp of Hungary in the final.

Torres trained at the Empire Sporting Club in New York City. He was the 1958 National AAU Middleweight Champion and also won the 1958 New York Golden Gloves 160 lb Open Championship.

He debuted as a professional in 1958 with a first round knockout of George Hamilton in New York. Twelve wins in a row followed, ten of them by knockout (including wins over contenders Ike Jenkins and Al Andrews), after which he was able to make his San Juan debut against Benny Paret, a world welterweight and Middleweight champion whose death after a fight would later on become one of the turning points in the history of boxing. Torres and Paret fought to a ten round draw, and in 1960, Torres went back to campaigning in New York, where he scored three wins that year, all by decision, including two over Randy Sandy.
