History of Blogs

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 of 1999.This was quickly adopted as both a noun and verb ("to blog," meaning "to edit one's weblog or to post to one's weblog").OriginsBefore blogging became popular, digital communities took many forms, including Usenet, commercial online services such as GEnie, BiX and the early CompuServe, e-mail lists[48] and Bulletin Board Systems (BBS). In the 1990s, Internet forum software, such as WebEx, created running conversations with "threads". Threads are topical connections between messages on a metaphorical "corkboard".The modern blog evolved from the online diary, where people 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.[citation needed] Dave Winer's Scripting News is also credited with being one of the oldest and longest running weblogs.Early weblogs were simply manually updated components of common websites. However, the evolution of tools to facilitate the production and maintenance of web articles posted 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 of browser-based software is now a typical aspect of "blogging". Blogs can be hosted by dedicated blog hosting services, or they can be run using blog software, such as WordPress, Movable Type, Blogger or LiveJournal, or on regular web hosting services.Rise in popularityAfter a slow start, blogging rapidly gained in popularity. Blog usage spread during 1999 and the years following, being further popularized by the near-simultaneous arrival of the first hosted blog tools:* Open Diary launched in October 1998, soon growing to thousands of online diaries. Open Diary innovated the reader comment, becoming the first blog community where readers could add comments to other writers' blog entries.* Brad Fitzpatrick, a well known blogger started LiveJournal in March 1999.* Andrew Smales created Pitas.com in July 1999 as an easier alternative to maintaining a "news page" on a website, followed by Diaryland in September 1999, focusing more on a personal diary community.* Evan Williams and Meg Hourihan (Pyra Labs) launched blogger.com in August 1999 (purchased by Google in February 2003)

Blog

A blog (an abridgment of the term web log) is a website, usually maintained by an individual, with regular entries of commentary, descriptions of events, or other material such as graphics or video. Entries are commonly displayed in reverse chronological order. "Blog" can also be used as a verb, meaning to maintain or add content to a blog.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 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 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. Micro-blogging is another type of blogging which consists of blogs with very short posts. As of December 2007, blog search engine Technorati was tracking more than 112 million blogs.[1] With the advent of video blogging, the word blog has taken on an even looser meaning of any bit of media wherein the subject expresses his opinion or simply talks about something.

Personal Blog

The personal blog, an on-going diary or commentary by an individual, is the traditional, most common blog. Personal bloggers usually take pride in their blog posts, even if their blog is never read by anyone but them. Blogs often become more than a way to just communicate; they become a way to reflect on life or works of art. Blogging can have a sentimental quality. Few personal blogs rise to fame and the mainstream, but some personal blogs quickly garner an extensive following. A type of personal blog is referred to as "microblogging," which is extremely detailed blogging as it seeks to capture a moment in time. Sites, such as Twitter, allow bloggers to share thoughts and feelings instantaneously with friends and family and is much faster than e-mailing or writing. This form of social media lends to an online generation already too busy to keep in touch.
