Web 2.0 is a word used to describe the interactive and collaborative nature of the Internet in its current form. It represents a shift from the static, one-way communication of the past to a dynamic, two-way platform that encourages user-generated content and social networking. Web 2.0 sites, such as social media and blogging platforms, allow users to create and share content, connect with others, and collaborate in real time. This has led to a democratization of content creation and communication, where anyone can become a publisher and share their ideas with the world. Web 2.0 has also significantly impacted business and marketing, opening up new opportunities for companies to reach their target audience through social media marketing, influencer marketing, and content marketing. Overall, Web 2.0 has transformed how we use the Internet and opened up new opportunities for communication, collaboration, and innovation.
