For example, the ABS - CBN drama Mara Clara, running from 1992 to 1997, gained nationwide popularity due to the intense rivalry between Judy Ann Santos as the protagonist Mara and Gladys Reyes as the evil antagonist Clara. The series became the longest - running post-Martial Law telenovela in Philippine television history, and had experienced frequent timeslot changes before settling into the standard 7: 00 P.M. - 8: 00 P.M. primetime block by late 1995. Mara Clara is also credited for being the country's first ever successful telenovela to spawn a similarly successful movie (under the same name).
