“The Evolving Internet,” a new study recently released by Cisco and the Monitor Group’s Global Business Network, predicts the internet is in for dramatic changes by the year 2025.

The most important factor in any path the internet takes is the location of its users. Cisco’s report predicts the next two or three billion web users will mostly live in developing markets. “Most growth in the internet-related market will occur outside of today’s high-income, or ‘advanced,’ economies,” according to the report.

This could have serious implications on what the internet will look like 15 years from now, said the report’s co-author and Cisco’s director of strategy and economics for emerging markets Enrique Rueda-Sabater. He said business models and policies will have to change across the globe in order to keep up.

Changes to the internet will also be determined by the improving technology that make devices and connecting to the web more affordable, the report says.

A report published in PC World earlier this month commemorated the 40th anniversary of the internet’s creation. Since 1969, the web has gone from a single connection between two computers to the two-billion-user behemoth it is today.
