The adidas tango is a successful family and brand of association football balls originally introduced as the tango durlast in 1978, specifically for the 1978 fifa world cup in argentina. Variations of the design had been produced for various competitions including the fifa world cup, the uefa european championship, and the football competition of the summer olympics. The tango balls have had different names applied to them to distinguish them in their construction, the competitions they have been used for, and even if they are official match balls or replica balls.
In 2011, adidas introduced the new tango 12 ball, but aside from the name there are no particular similarities between the new ball and the old adidas tango family.
