Web1, or Web 1.0, is the term commonly used to describe the first stage of the World Wide Web's evolution. Think of Web1 as the "read-only" web, which primarily consisted of static websites that were used for consuming information rather than interactive experiences. Here's what characterized Web1:

1. **Static Content**: Websites were made up of static HTML pages that displayed the same content to every visitor. They were not interactive beyond basic hyperlinks and form submissions.

2. **Limited User Interaction**: There was minimal user interaction or engagement. Users could read or download content but not much else. There were no like buttons, comment sections, or user-generated content.

3. **Directory-Based Navigation**: Web directories, such as Yahoo!, were popular, which categorized websites into a hierarchical structure as opposed to using search engines.

4. **Content Creators and Consumers**: The content was created by a relatively small group of people, with the vast majority of users acting as consumers of that content.

5. **Simple Design**: Web design was relatively simple, with little attention paid to aesthetics or user experience. This was partly due to the limitations of early HTML and internet speeds.

6. **No Social Media**: Social media platforms as we know them did not exist. While there were online communities and forums, they were not integrated into the web's fabric.

7. **No Mobile Web**: The internet was accessed almost exclusively through desktop computers, as mobile phones at the time did not have the capability to browse the web.

8. **Dial-up Connections**: Many users accessed the internet using dial-up connections, which were slow by today's standards and tied up the phone line.

Web1 lasted from the early 1990s until the early 2000s when it began to evolve into Web 2.0. The transition to Web 2.0 wasn't a clear-cut changeover but rather a gradual shift as technology improved and new web development practices emerged. Web 2.0 brought a more interactive and social web, with user-generated content, social media platforms, blogs, wikis, and other features that allowed for greater user participation and collaboration.
