It is a core technology of the Web page design. Its core aims to improve the language with support for the latest multimedia devices. The Web Hypertext Application Technology Working Group (WHATWG) began work on the new standard in 2004. Now W3C and WHATWG are currently working together on the development of HTML5. HTML5 is often compared to Flash but these two technologies are different to each other. it became the topic of mainstream media around April 2010, after Apple Inc’s CEO “Steve Jobs” issued a public letter titled “Thoughts on Flash” where he concludes that “Flash is no longer necessary to watch video or consume any kind of web content” and that “new open standards created in the mobile era, such as HTML5, will win”. According to a report released on 30 September 2011, the world’s top 100 Web sites were using HTML5. HTML5 introduces elements and attributes that reflect typical usage on modern websites. It adds many new syntactic features. These features are designed to make it easy to include and handle multimedia and graphical content on the web without having to resort to proprietary plugging and APIs.
