AT&T Argentina (Argentina)

AT&T Argentina was an AT&T television service/promo placeholder in Argentina. Founded in January 1, 1969 when Saul Bass designed the stylized bell logo, was named "Atodo Color", possibly despite is a subsidiary of Atod Television located in argentina. It can be spelled as ATodo Color. In May 14, 1982 it was sold to Bell System to form Bell System Argentina, and later in February 17, 1983 to AT&T to form AT&T Argentina, one of the Latin America's "baby bells". They adopted the 1983 logo in the same year, but in August 29, 1983.

1969-August 23, 1971
Simplistic but effective, they did not use a logo until August 23, 1971. They used only a color card like this one showed in the left and only indicated color broadcasting.

August 23, 1971-1975
The rest is coming soon. Please update this if you can.
