Blogs in general
Blog is the contraction universally used for weblog, a type of website where entries are made (such as in a journal or diary), displayed in a reverse chronological order.
Blogs often provide commentary or news and information on a particular subject, such as food, politics, or local news; some 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. Most blogs are primarily textual although some focus on photographs (photoblog), videos (vlog), or audio (podcasting), and are part of a wider network of social media.
The word blog can also be used as a verb, meaning to maintain or add content to a blog.
Before blogging became popular, digital communities took many forms, including Usenet, e-mail lists 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. A few called themselves escribitionists. The Open Pages webring included members of the online-journal community. Justin Hall, who began eleven years of personal blogging in 1994 while a student at Swarthmore College, is generally recognized as one of the earliest bloggers.1
