How does the cloud differ from the World Wide Web of the 1990s?

ARPANET and NSFNET were sold to ISP's and became the commercial internet of the 90's. At this time, no resources were provided. Media and information was contained within webpages of websites. They used HTTP/HTTPS for access and were hosted on web servers. This was called the World Wide Web. Search engines, Office 365, video streaming, personal banking, social media, smartphones, and smart assistants among many other programs that process/communicate information/media are collectively referred to as web apps. They are programs on web servers that can be accessed by computers/IoT devices across the internet via a browser, mobile app, or client program. If the web server contains a program that facilitates this, it is referred to as a cloud server and the worldwide collection of cloud servers is referred to as the cloud.
