A blog (a blend of the term web log) is a type of website or part of a website. Blogs are usuallymaintained by an individual with regular entriesof commentary, descriptions of events, or other material such as graphics or video. Entries are commonly displayed in reverse-chronologicalorder. Blog can also be used as a verb, meaning to maintain or add content to a blog. http://en.wikipedia.org/wiki/Blog
Most blogs are interactive, allowing visitors to leave comments and even message each other via widgets on theblogs and it is this interactivity that distinguishes them from other static websites.
Many blogs provide commentary or news on a particular subject; others function as more personal online diaries. A typical blog combines text, images, and links to otherblogs, Web pages, and other media related to its topic. The ability of readers to leave comments in an interactive format is animportant part of many blogs. Most blogs areprimarily textual, although some focus on art (art blog), photographs (photoblog), videos (video blogging or vlogging), music (MP3blog), and audio (podcasting). Microblogging is another type of blogging, featuring very short posts.
The term "weblog" was coined by Jorn Barger on 17 December 1997. The short form, "blog," was coined by Peter Merholz,who jokingly broke the word weblog into the phrase we blog in the sidebar of his blog Peterme.com in April or May 1999. Shortly thereafter, Evan Williams at PyraLabs used "blog" as both a noun and verb ("to blog," meaning "to edit ones weblog or to post to ones weblog") and devised the term "blogger" in connection with Pyra Labs Blogger product, leading to the popularization of the terms.
Origins Before blogging became popular, digital communities took many forms, includingUsenet, commercial online services such as GEnie, BiX and the early CompuServe, e- mail lists and Bulletin Board Systems (BBS). In the 1990s, Internet forum software, created running conversations with "threads." Threads are topicalconnections between messages on a virtual "corkboard."
The modern blog evolved from the online diary, wherepeople would keep a running account of their personal lives. Most such writers called themselves diarists, journalists, or journalers. Justin Hall, who began personal blogging in 1994 while a student at Swarthmore College, is generally recognized as one of the earliest bloggers, as is Jerry Pournelle.Dave Winers Scripting News is also credited with being oneof the oldest and longest running weblogs. Another early blog was Wearable Wireless Webcam, an onlineshared diary of a persons personal life combining text, video, and pictures transmitted live from a wearable computer and EyeTap device to a web site in 1994. This practice of semi-automated blogging with live videotogether with text was referred to as sousveillance, and such journals were also used as evidence in legal matters.
Early blogs were simply manually updated components of common Web sites. However, the evolution of tools to facilitate the production and maintenance of Web articlesposted in reverse chronological order made the publishing process feasible to a much larger, less technical, population. Ultimately, this resulted in the distinct class of online publishing that produces blogs we recognize today. For instance, the use of some sort ofbrowser-based software is now a typical aspectof "blogging". Blogs can be hosted by dedicatedblog hosting services, or they can be run using blog software, or on regular web hosting services.
Some early bloggers, such asThe Misanthropic Bitch, who began in 1997, actually referred to their onlinepresence as a zine, before the term blog entered common usage.
