The idea of the show came from two sources. Originally, producer Gabriel Suau approached
Antonio Sánchez with the idea of a talk show called
No te Duermas. Suau wanted to have
Axel Anderson as host while Sánchez would intervene with
comedy sketches, characters and interrupting the interviews. Sánchez, instead, presented Suau an idea he had for a show. Suau then decided to drop his original idea and gave Sánchez the opportunity to lead it. In February 1990, the show debuted in Channel 7 (
Super Siete) instantly peaking at #1 in local popularity charts. After a year,
Telemundo made Suau an offer and the show moved in October 1991. The show continued to be #1 for two years, and stayed on the Top 10 for the following years. In 2005, while negotiating their contract, Telemundo offered Sánchez the chance to do the program from Monday to Friday, and compete directly with
Univision's ''
Anda Pa'l Cara. Sánchez accepted, changing also the overall format of the show. In February 2008, the show changed to a Monday through Thursday format, with Esto Esta Kñon'', a political discussion and satire show, aired on Friday. This show is produced by Antonio Sánchez himself. Near the end of 2008, Sánchez announced he would retire the show after almost 19 years. During December 2008, the show featured interviews with people that contributed to the show's success during its history, and shows of old comedy sketches. The last show was aired on December 30, 2008.
Antonio Sánchez "El Gangster" returned with a live show called "No Te Duermas: Una noche más" August 31, 2019 at the
Coliseo de Puerto Rico and included a live feed to a location in
Orlando, Florida (to accommodate the many Puerto Ricans who have migrated there). The show hosted the same scenery, characters and humor that distinguished the television program, and then was aired on September 17, 2019, on
WAPA TV. ==Hosts and models==
