Gates identifies the Internet as a technological change significant enough to alter the direction of the computer industry. By comparing it with the introduction of the IBM PC in 1981, he places networked communication alongside an earlier development that helped bring personal computing into widespread use. He goes further by describing the Internet as more consequential than the graphical user interface, another major change in how people interacted with computers.

In The Internet Tidal Wave, this assessment supports a broader strategic argument. Gates tells Microsoft’s leadership that Internet capabilities must become important across the company rather than remain a separate initiative. The quote therefore concerns both technological change and organisational response: recognising when a new platform or infrastructure is likely to reshape established products, markets and user behaviour. It can be applied to discussions of technological turning points and how organisations decide when an emerging technology requires a fundamental change in strategy.

“Now I assign the Internet the highest level of importance. In this memo I want to make clear that our focus on the Internet is crucial to every part of our business. The Internet is the most important single development to come along since the IBM PC was introduced in 1981. It is even more important than the arrival of graphical user interface (GUI).”
