A weblog (usually shortened to blog, but occasionally spelled web log or weblog) is a web-based publication consisting primarily of periodic articles, most often in reverse chronological order. 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 said chronological fashion 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 on regular web hosting services.
