The network of Spanish neology observatories, Antenas Neológicas, was created in 2002. In addition to Barcelona, as the coordinating node, universities in Argentina, Colombia, Cuba, Mexico, Peru, Uruguay and Chile were part of the network in those early years. Twenty years later, the continuity and strengthening of the network and its achievements are being celebrated, thanks to the constant efforts of many people and many work teams.

The celebration took place in Valparaiso, at the closing of the II Seminario Internacional de Neología, where the testimonial video was published.
