Posts are typically displayed in reverse chronological order, so that the most recent post appears first, at the top of the web page.
The emergence and growth of blogs in the late 1990s coincided with the advent of web publishing tools that facilitated the posting of content by non-technical users who did not have much experience with HTML or computer programming.
Many blogs provide commentary on a particular subject or topic, ranging from politics to sports. Others function as more personal online diaries, and others function more as online brand advertising of a particular individual or company. A typical blog combines text, digital images, and links to other blogs, web pages, and other media related to its topic.
The earliest instance of a commercial blog was on the first business to consumer Web site created in 1995 by Ty, Inc., which featured a blog in a section called “Online Diary”. The entries were maintained by featured Beanie Babies that were voted for monthly by Web site visitors.
Personal blogs
The personal blog is an ongoing online diary or commentary written by an individual, rather than a corporation or organization. While the vast majority of personal blogs attract very few readers, other than the blogger’s immediate family and friends, a small number of personal blogs have become popular, to the point that they have attracted lucrative advertising sponsorship.
Collaborative blogs
A type of weblog in which posts are written and published by more than one author. The majority of high-profile collaborative blogs are based around a single uniting theme, such as politics, technology or advocacy. In recent years, the blogosphere has seen the emergence and growing popularity of more collaborative efforts.
Microblogging
Microblogging is the practice of posting small pieces of digital content—which could be text, pictures, links, short videos, or other media—on the Internet. Microblogging offers a portable communication mode that feels organic and spontaneous to many users. It has captured the public imagination, in part because the short posts are easy to read on the go or when waiting.
As the popularity of blogging continues to rise, the commercialisation of blogging is rapidly increasing. Many corporations and companies collaborate with bloggers to increase advertising and engage online communities towards their products.
