Web 2.0 allows interactivity, social connectivity, and also promotes user-generated content. The user-generated contents are stored in a database, and made available to other users instantly. While Web 1.0 was primarily used on desktop computers, Web 2.0 has advanced to support mobile devices like smartphones and tablets; and the web pages are designed to display content responsively whether it was shown on a computer, tablet, or phone.
Web 2.0 also contributed to the exponential growth of social media networks. Dynamic interactivity over mobile devices allows users to contribute texts, photos, and videos on the social media platforms like Facebook, Instagram, TikTok, and Twitter. The advent of Web 2.0 was largely contributed by FAANG, a group of five largest companies in the USA: Meta (META, known as Facebook), Amazon (AMZN), Apple (APPL), Netflix (NFLX) and Alphabet (GOOG).

The original web 1.0 was primarily designed to display "static" web pages without many user interactions. The original web 1.0 was supported by browsers like Netscape Navigator and Microsoft Explorer.
