Content development is quite complex and creative work. The contribution of quality information to the promotion, description of the product or the development of instructions should be as informative, short and understandable as possible. Content can be expressed through any means, such as speech, letter, presentation, application, or website. Typical forms of content creation include support for and updating sites, blogs, writing articles, photo, video, online commentary, support for social media accounts, and media editing and distribution.
