Instead the researchers sought to create an open network for freely exchanging information, an openness that ultimately spurred the innovation that would later spawn the likes of YouTube, Facebook and the World Wide Web.
There's still plenty of room for innovation today, yet the openness fostering it may be eroding. While the Internet is more widely available and faster than ever, artificial barriers threaten to constrict its growth.
Call it a mid-life crisis.
A variety of factors are to blame. Spam and hacking attacks force network operators to erect security firewalls. Authoritarian regimes block access to many sites and services within their borders. And commercial considerations spur policies that can thwart rivals, particularly on mobile devices like the iPhone.
"There is more freedom for the typical Internet user to play, to communicate, to shop - more opportunities than ever before," said Jonathan Zittrain, a law professor and co-founder of Harvard's Berkman Center for Internet & Society. "On the worrisome side, there are some longer-term trends that are making it much more possible (for information) to be controlled."
