Until August 2020, Arrarás spent two decades as the host and managing editor of Al Rojo Vivo con María Celeste.

She also launched her YouTube channel and premiered MC Live, a weekly one-on-one interview program that quickly surpassed 1 million views.

[8] Arrarás began her broadcasting career in 1986 when she was employed by a local Puerto Rican television station, Channel 24, as a news anchor and reporter.

[9] There, Arrarás traveled covering major news events, such as the fall of the Soviet Union in Moscow and Leningrad, and she received several journalistic awards for her reports.

[12] The defection of María Celeste Arrarás from Univision, North America's largest Spanish-language network, to the rival Telemundo broadcasting group in 2002 sent shockwaves in the industry and was heralded as the start of a new era for Hispanic media.

[17] On the night of María Celeste's debut as a contributor for Dateline NBC, the show experienced a dramatic audience increase in both Hispanic and Anglo demographics.

NBC president Andrew Lack told the Los Angeles Times, "[María Celeste] was one of the highest segments at Dateline that quarter."

One news source stated, the addition of María Celeste is the latest development in a strategy that consolidated "Noticiero Telemundo" as the national newscast with the fastest growing audience on both Spanish and English-language television.

[22] In the summer of 2016, Arrarás celebrated her 30-year career in television, and was reunited with her former co-host of Primer Impacto, Myrka Dellanos, for a special edition of Al Rojo Vivo commemorating the anniversary.

[25] As of the Summer of 2021 Arraras will be part of the staff of CNN en Español, as the host of their Sunday Prime Time show called DocuFilms con María Celeste Arrarás.

In 2021, she also launched her YouTube channel and premiered MC Live, a weekly one-on-one interview program that quickly surpassed 1 million views.

Often cited as the “Hispanic TV Queen”, Arrarás has been described by The New York Times as “a household name in Spanish-speaking homes across the country, and a darling of the Spanish-language media, which turned her into a cover girl for magazine articles that ranged from fitness to the supermom syndrome".

[35] In December 2001, she even went in front of the Puerto Rican Legislature to advocate for a ban in the Island on circuses that forced wild animals to perform as part of their shows.

[36] Maria Celeste is a supporter of Para la Naturaleza, a non-profit organization dedicated to environmental conservation and historic preservation in Puerto Rico.
