Geloso had as consequence the study and construction of receivers and transmitters for the radio amateurs range further to pilot groups (VFO) and other detached parts useful for a lot of amateurs around the world to realize their own receiving –transmitting station: Geloso was called in the slang of radio amateurs during their conversations as the “ well known House” for antonomasia. During the Trade Fair of Radio and Television of Milan in April and in September 1968 the public and the technicians could appreciate the receivers for the colour television that started to be studied since many years and brought to the elaboration of circuits with new original solutions. This new field of activity required relevant investments and care. Fine and huge premises for the product distribution were build in main Italian cities; each one of them had everything that was necessary to satisfy the customers properly: travellers, 
offices, stores and a settled and travelling service of technical assistance equipped with all the suitable instruments. The premises were: Torino, Genova, Padova, Bologna, Firenze, Ancona, Pescara, Napoli, Bari, Cosenza and Cagliari.

In order to have a stronger commercial holding in north America were created the “American Geloso Electronics” and the “Canadian Geloso Electronics”; in south America there were local firms with the name of Geloso in Argentina, Uruguay, Peru. In this way Geloso was spreading his products around the world developing our fame of industrial nation. Geloso was present also in the main industrial and economical review.
