What is the difference between websites and blogs?

In recent years, blogs have become increasingly popular. Seeing the popularity, some might wonder, what is the difference between a blog and a traditional website? After all, a blog is quite literally a website, so perhaps the question should be what makes a blog unique? Blogs tend to be webpages written and edited by a single person, and usually focus entirely on one topic. CNN is not a blog, as it represents the shared creation between writers, photographers, web designers, and more recently its audience. The most popular blogs these days tend to be those written about celebrities. Perez Hilton is a good example of a celebrity blogger. He write all his own articles, meaning what you see, hear, and read is entirely shaped by Perez himself. Blogs also have an intrinsically social aspect to them as well, as they have typically contained a function to allow commenting which enables broader discussion among viewers, and with their author. This feature is now being adopted by more traditional websites, such as CNN with discussion boards and even iReports (reports done by readers, not trained journalist). These changes are happening because of the success of blogs, not in spite of them. Blogs are able to convey a human voice which feels comforting to readers, which is why we cannot help but go back continuously to our favorite sites. Traditional websites have noted the popularity, and are now adapting their designs to fit this new model. The definition of blog and website are blending so much that soon they will be synonymous.
