Was created in 1995 by Jose Artemio, originally named as Gran Santiago Television (GSTV) and broadcasting in UHF. On 2000, the channel is adquired by Universidad Nacional Andres Bello, and is renamed as Andres Bello Television (ABT). In 2005, is bought by Optima Producciones, and is rebranded as Television Optima (TVO). By 2006, the channel was named as Mas Canal 22, after being adquired by El Pabellon de la Construccion.
