Televisión Independiente de México (Independent Mexican Television, known on air as TIM or Cadena TIM) was a Mexican national television network founded in 1965 by Eugenio Garza Sada. It operated until 1973, when it merged with its primary competitor, Telesistema Mexicano, owned by Emilio Azcárraga Vidaurreta, to form the Televisa conglomerate. Televisa absorbed all of TIM's assets, including its television transmitters and its series, including pioneering programs such as El Chavo del Ocho.
