It started in the '70s as a military project, morphed in the 1980s to an academic network, co-opted by commercial companies in the '90s, and then invaded by all of us via social media in the noughties, but I think it's going to change again.
È iniziato negli anni '70  come un progetto militare, cambiato negli '80 in un network accademico, cooptato dalle compagnie commerciali negli anni '90, e infine invaso da tutti noi tramite  i social media in questo decennio, ma penso che stia per cambiare ancora.
