What are online tools that allow users to publish and share content called?

The correct answer is social media. Social media platforms are specifically designed to enable users to create, publish, and share a variety of content, encompassing text, images, videos, and more. These platforms not only facilitate immediate communication and interaction among users but also encourage the dissemination of content across a wide audience. They are characterized by their ability to foster community and interaction, allowing individuals and organizations to engage directly with their followers or the general public.

While websites can cover a broad range of content and purposes, not all websites have interactive capabilities or content-sharing features typical of social media. Blog platforms primarily focus on written content with features geared towards blogging, but they may not encompass the wider interaction and sharing elements that social media offers. Forums allow for discussion and exchange of information but are generally more structured around topics rather than the diverse content-sharing capabilities of social media platforms.
