Web 1.0 allowed only one-way consumption of content while Web 2.0 enabled user-generated content through tools like blogs and social media. Web 3.0 will connect all this data through applications and widgets that are location-aware and personalized. It will understand semantics to provide intelligent, contextualized search and recommendations tailored to individual users through social profiles and activity on various connected devices and platforms. Commerce will also change as companies target niche audiences through new forms of advertising integrated with popular personalities and content.
