WordPress is an “Open Source” development platform basically used to build websites and blogs. Initially the platform was introduced to create a blog. Later it turned into a powerful web development tool. Today’s WordPress is really a “content management system” (CMS), which means that it can be used to run full-sized, social media-rich business websites.
WordPress designs are based on “Themes”. Themes are predefined images or CSS webpage layouts used to customize the look and feel of a WordPress website. One of the main reasons behind the popularity of WordPress is its easy-to-use functionality. Developing a website with this platform barely require any coding knowledge. You can create a website or blog right into the browser. Because the interface is web-based, creating and editing pages can be done from anywhere with an Internet connection.
The platform was introduced by Matt Mullenweb and Mike Little, as a fork of B2/Cafelog. The platform keeps upgrading quite frequently. Currently, the latest version is 3.7 which has been downloaded nearly 10 million times as of Nov 2013.
