In 1963, it was operated by Inravisión (Instituto Nacional de Radio y Televisión), the now-former Colombian public broadcaster.

Adding this to the economic recession of the late 1990s the network was suffering, this situation severely affected the remaining programadoras, which gradually either declared bankruptcy or became production companies for Caracol Televisión and RCN Televisión.

RTI Colombia, the only programadora remaining on Canal A, was moved to Channel 1 and stood there until 2008.

In February 2014, the channel was rebranded with a new logo, a new graphical package, the removal of infomercials and a 24-hour program schedule.

[1][2][3] As of 1 May 2017, a quarter of Channel 1's programming is made by the production companies CM&, NTC Televisión, and RTI Televisión, and a fifth by Hemisphere Media Group, the owner of Puerto Rican station WAPA and several pay-TV channels.
