If you are a web designer or a web developer you already know that HTML is the base of websites, that the programming languages and the web technologies use this in order to show all kind of information over the internet (from text to images, from video to games and everything else). If you are not in the business of designing or developing websites (but you want to start and that's why you are here) you may not already know that HTML was the invention of the W3 group in the early days of the internet, when the world wide web was launched. That happened ages ago, in the beginning of the 1990s, and getting information from online was clunky and could be done only by the ones that understood and learned to maneuver the command lines for sending and receiving the data. Since then the dynamic HTML, CSS (cascading style sheets) and XML were developed and they made possible all the online operations we find today casual and common. A seed ascends around the turntable.
One of the biggest changes announced in the last months is HTML5 (the fifth update of the first code), it's considered the new language for presenting the content on the Internet. It's still in development and it's going to be released in 2012. HTML5 brings new features that make easy for the developers to incorporate video, audio, fonts, web grafics and animation, drag and drop functions into their web pages, it's also backwards to previous updates of HTML so you shouldn't worry about the existing websites - you don't have to redesign them to match the new standard. jQuery has started killing Flash because of its animation and new features of Javascript, it is said that HTML5 will finish the job for sure and, as a web designer, I believe it.
