Il videoregistratore domestico festeggia i suoi primi 40 anni anche se oggi è stato soppiantato da DVD e streaming. Era il 1975 quando Sony lanciava il Betamax (il 10 maggio in Giappone, il 7 giugno negli USA e tre anni dopo in Europa), innescando una rivoluzione nei consumi.
Contemporaneamente fu lanciata anche la prima grande “guerra” tra formati elettronici. Una guerra per la conquista del mercato dell'home video che il Betamax, da pioniere, perse davanti a un altro formato: il VHS, lanciato ad appena un anno dopo, ebbe la meglio sul formato di Sony per elementi tecnici ma soprattutto per le scelte adottate da JVC la casa di produzione del sistema.
In più sul formato di Sony cadde una scure legale non da poco: Universal Studios e Disney avviarono una causa sulla possibilità che gli utenti potessero registrare materiale con copyright. Solo nel 1984 il videoregistratore fu dichiarato “non colpevole” di pirateria.
