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.
它在70年代由一个军事项目而启动， 在1980年代转变成了学术网络， 90年代被商业公司合作经营， 现在被我们所有人以社交网络入侵， 但是我觉得它还会改变。
