FYI, The Internet is the successor to arpanet, beginning with Honeywell IMPs, etc. over 30 years ago, NOT with Tim Berners-Lee and his www app that ran over the net, which he did at CERN in the 80's. There are also many other protocols besides http using the foundation of the Internet. Most people did not have access to the Internet until it was opened up to the public for domains in addition to university and military in the 90s.
