History

Internet connectivity options from end-user to ISP Tier 3/2

Originally, to access the Internet you needed a university or government agency account; that necessarily had to be authorized. The Internet began accepting commercial traffic in the early 1990s, but it was too limited and minimal compared to today. In those days there was a small group of companies, called access points, which provided public access but became saturated once the traffic increased. The largest telecommunications companies began to provide private access. Small companies benefited from the access to the network of the big companies, but then the big companies began to charge for this access. All of this around the mid-1990s, before the internet blew up.

When the Internet suddenly evolved, ISPs were drastically challenged to upgrade their infrastructure, technologies, and increase their access points. The largest communications companies began to develop subsidiaries that focused on making the Internet a more accessible medium. Although the technology was updated, the web had to deal with more and more congestion.
