Technorati

Technorati, founded in 2002 by Dave Sifry, began as the first real-time blog search engine. It focused on indexing and categorizing blogs to highlight the global online conversation. Over the years, Technorati evolved into a full-service media company, providing valuable services to blogs and social media sites while connecting them with advertisers. The company offered a blog search engine that allowed users to discover blog content in real-time, which was especially important during the rapid growth of the blogosphere. Technorati also provided analytics and historical data on blog trends and traffic, catering to both small bloggers and major news outlets. In 2009, it launched Technorati Media, a social media ad network that helped bloggers and content creators secure brand advertising, serving billions of ads across thousands of sites each month.
