During the course of the company’s history, APA has developed some unique perimeter systems. The APA roto-system® was installed throughout Europe in the 1990s, and the first LED banner with SMD technology at the beginning of the 2000s. And in 2011, for the World Skiing championships in Garmisch-Partenkirchen, we designed and patented the APA radial air cushions for the European Broadcasting Union (EBU) in cooperation with Tridem Sports AG, increasing the advertising area from 1.3 to 2 metres with no change in height. Three years later, in collaboration with the winter sports marketers Infront, the Biathlon World Cup benefited from the APA LED light banner. This guarantees increased visibility during adverse weather conditions and evening events. This system was further developed for the women‘s tennis tournament in Stuttgart. Last but not least, at Borussia Dortmund in 2016, the first 1.20 meter high SMD video banner using 10mm technology was used around the entire playing field, creating a new benchmark for Bundesliga football.
