Televisión Independiente de México
Another company named Televisión Independiente de México was originally founded as as a one channel in 1968. The logo consisted as the T, I and M letters were merged into a single form, and the white circle covered the letter I letting two remaining letters.

This was first logo with the eye symbol inspiration from CBS making as an orange oval broken into ten lines with the sun in the scenery. The eye logo was designed by Pedro Ramírez Vázquez, symbolizing as the spectator's vision to watch the world throughout the television.
The 1973 logo was with wordmark using as a separated name as "Tele Visa" that was stacked without the letter "I", and using the same name of the defunct Venezuelan TV channel. The letter "T" was an two striped cross unified with the letter "V" and "I" as the letter "t" in lowercase.
The wordmark was discontinued in 1981, and the empty space of the sun was colored yellow. This logo was still used as a secondary variation, seen in some idents until 2001.
Televisa launched a new logo on January 1st, 2001, putting eight lines instead of ten, and it's similar to the previous logo, just the frequent changes from the next two logos.
Changes include the sun now being a 3D sphere, which in turn making the logo an eye, and the wordmark was Helvetica Black.
