Rayos X

Jay Fonseca had hosted a political analysis and interview segment on the daytime talk show Dia a Dia called "De Frente con Jay Fonseca" (Upfront with Jay Fonseca) for years on Telemundo Puerto Rico before the station agreed to produce a spinoff of the segment as an investigative journalism program. The show was originally announced in December 2013 during the stations upfront presentation and it was meant to premiere in 2014 but the production was delayed and the show did not premiere until fall 2015. In September 2015, Telemundo announced the premiere of the show would finally take place on October 13, 2015. The show's premiere took place on a Tuesday immediately after Raymond y sus Amigos but the station announced that the show was scheduled to air Thursdays at 9:00 p.m. thereafter.^[2][3][4][5]

Fonseca would host alongside a crop of new journalists such as Tatiana Ortiz (now a reporter for NotiCentro on WAPA), Valeria Collazo and Alexandra Acosta. In 2016, just a year after the show's premiere Telemundo would announce that the show would move permanently to Tuesdays at 10:00 p.m. to create a block of 4 hours of live original local programming which would feature Raymond y sus Amigos (which would serve as the show's lead-in), Jay y sus Rayos X and Telenoticias (the station's newscast). The show officially moved to its new time on July 12, 2016.^[6]

The special called Jay y sus Rayos X: La última opportunidad (Jay and his X Rays: Last Chance) featured Pedro Pierluisi, Carlos Delgado Altieri, Alexandra Lúgaro, Eliezer Molina and Cesar Vazquez and was focused on asking the candidates questions related to corruption and proposals for growth of the island.^[7]

On July 15, 2021, Jay Fonseca officially declined to renew his contract and would leave both Rayos X and Dia a Dia effective immediately. Fonseca's came after an offer from rival station WAPA where he now hosts a daily show called Los datos son los datos (Facts are Facts) and a weekly investigative journalism show called Cuarto Poder (Fourth Power).^[8][9]
