The word ‘blog’ is derived from the combination of the two words, web and log.
Blogs can be virtual diaries, commentaries on a particular subject, or even an editorialized view on current events. It's a space to voice your opinions and share them with millions of potential readers.
A typical blog combines text, images, and links to other blogs, web pages, and other media related to its topic. The ability for readers to leave comments in an interactive format is an important part of most blogs. Most blogs are primarily textual although some focus on photographs (photoblog), sketchblog, videos (vlog), or audio (podcasting), and are part of a wider network of social media.
