Blogs have become a popular way for individuals and organizations to share information online. They originated from online diaries and journals known as web logs that allowed users to post entries comprising links, text and photos. Over time, blogs evolved to include various types like personal blogs, news blogs, photoblogs and network blogs hosted on sites like CNN, MTV and Blogger. Photoblogs in particular gained popularity by using photos instead of just text to convey ideas. Blogs are widely used today due to their low cost, ease of maintenance and ability to connect with audiences on both personal and business levels.
