 TELSTAR 18:

The Adidas Telstar 18 is the official match ball of the 2018 FIFA World Cup, which will be held in the Russian Federation. It is designed by the company Adidas, a FIFA Partner and FIFA World Cup official match ball supplier since 1970, and based on the concept of the first Adidas's World Cup match ball.
The Telstar 18 was presented in Moscow on November 9, 2017 by Lionel Messi.

The name of the ball was revealed on November 9, 2017 at the official presentation in Moscow by Lionel Messi, winner of the Golden Ball at the 2014 FIFA World Cup, and attended by winners of the World Cup in different years: Zinedine Zidane, Kaká, Alessandro Del Piero, Xabi Alonso and Lukas Podolski The Telstar 18 pays homage to Adidas's first World Cup match ball, named the Telstar, which was itself named for its resemblance to the original Telstar communications satellite The word "Telstar" is a combination of the words "television" and "star.

Design

The original Telstar used in the 1970 FIFA World Cup was the first football to show a black and white pattern. This was done to ensure that television audiences would know where the ball was while games were in operation, due to many televisions at the time sporting a black and white screen (colour television was still rare in many parts of the world in this era). Although the Telstar had 32 panels, the Telstar 18 has six textured panels. They are not stitched, but seamlessly glued together.
The ball has an embedded near-field communication (NFC) chip. However, it is of no value to players, providing no information about their kicks or headers of the ball, although Adidas has provided this in a previous football. Consumers who purchase a Telstar 18 are able to connect to the chip using a smart phone to access content and information that is unique to that ball, personalized and localized, providing the consumer with interactivity themed on the upcoming World Cup competition.
