A blog (a truncation of the expression weblog) is a discussion or informational website published on the World Wide Web consisting of discrete, often informal diary-style text entries ("posts").

Posts are typically displayed in reverse chronological order, so that the most recent post appears first, at the top of the web page.

Until 2009, blogs were usually the work of a single individual, occasionally of a small group, and often covered a single subject or topic.

In the 2010s, "multi-author blogs" (MABs) have developed, with posts written by large numbers of authors and sometimes professionally edited.

MABs from newspapers, other media outlets, universities, think tanks, advocacy groups, and similar institutions account for an increasing quantity of blog traffic.

The rise of Twitter and other "microblogging" systems helps integrate MABs and single-author blogs into the news media.

Blog can also be used as a verb, meaning to maintain or add content to a blog.

A podcast is an episodic series of digital media files which a user can set up so that new episodes are automatically downloaded via web syndication to the user's own local computer or portable media player.
