Blogging , too, has become a pervasive form of media. A blog is a website, usually maintained by an individual, with regular entries of commentary, descriptions of events, or interactive media such as images or video. Entries are commonly displayed in reverse chronological order, with most recent posts shown on top. Many blogs provide commentary or news on a particular subject; others function as more personal online diaries. A typical blog combines text, images and other graphics, and links to other blogs, web pages, and related media. The ability for readers to leave comments in an interactive format is an important part of many blogs. Most blogs are primarily textual, although some focus on art (artlog), photographs (photoblog), sketchblog, videos (vlog), music (MP3 blog), audio (podcasting) are part of a wider network of social media. Microblogging is another type of blogging which consists of blogs with very short posts.
If the entire process up to the stage of printing is handled by an outside company or individuals, and then sold to the publishing company, it is known as book packaging . This is a common strategy between smaller publishers in different territorial markets where the company that first buys the intellectual property rights then sells a package to other publishers and gains an immediate return on capital invested. Indeed, the first publisher will often print sufficient copies for all markets and thereby get the maximum quantity efficiency on the print run for all.
