HTML5: The next disruptive technology

  1. 1. University of Washington MCDMCOM585: Managing Your Web Presence October 31, 2012
  2. 2.  HTML5 is the latest version of HTML (defined as an application of Standard Generalized Markup Language) and XHTML (XML markup languages that mirror extended versions of HTML; an application of XML) 5th version of HyperText Markup Language  Not based on SGML (Standard Generalized Markup Language), but must be backwards compatible  Introduces new APIs, specific scripting that can be used with JavaScript (drag and drop, x-doc messaging) HTML5 is still in development, won’t be finished for a few years (2014 recommendation for HTML5.0) The core goal is to improve the language with support for the latest multimedia while keeping it easily readable by humans , computers and devices Adds new features: video, audio, canvas, SVG session storage, localStorage, geolocation Net result: more happens within the browser and locally on computers or devices, net: enables everything to happen more quickly, consistently, and efficiently Most mean HTML, CSS and JavaScript
  3. 3.  HTML4 recommended by W3C (Web Consortium) in 1997 Considered a rough guide on many of the core features of HTML – but does not go far enough HTML5 was started in 2004 by the WHATWG (Web Hypertext Application Technology Working Group)  Defines a single language called HTML that can be written in HTML syntax and XML syntac  Defines detailed processing models to foster interoperable implementations  Improves markup for documents  Introduces markup and APIs for emerging idioms such as Web applications
  4. 4.  Its not 1 big thing  Includes the Mobile Web  Native  Mobile Web  Hybrid  Apps  Instagram = native mobile app  LinkedIn & Facebook = hybrid  Tumblr = hybrid, mostly html5  Financial Times – html5  Kindle Cloud reader
  5. 5.  Infographic: HTML vs Flash Gaming industry pro Flash; New developers pro HTML5 Greater browser support for Flash (99%), but HTML5 (50%)is growing – making consistent headway in adoption rates (IOS/Android 8%) Apple has embraced HTML5 as an open source web technology for OS and web-enabled devices Ongoing HTML and Hybrid are young and evolving; mobile browsers are rapidly improving
  6. 6.  Distribution  Native apps are distributed via app stores, controlled by the owners of the platforms  HTML5 distributed via the rules of the open web, the link economy Monetization  Native apps come with one-click purchase options built into mobile platforms  HTML5 will be monetized via advertising because payments will be less user- friendly Platform power and network effects  Developers have to conform with Apple’s rules  Developers can cut Apple out of the loop with HTML5 reducing Apple’s platform Functionality  Now, native apps do more than HTML5 apps  HTML5 apps will get better
  7. 7.  Most popular types of apps will be early adopters  HTML5 is useful for media apps and access apps . Apps that display text, images and video and monetize via ads and subscriptions can be done more cheaply and effectively via HTML5 Increasing prevalence of “shell apps” (hyprid) will push things along HTML5 will improve, will be cheaper to produce = disrupter HTML5 comes from WC3 – which means the technology will evolve slowly
  8. 8.  What is HTML5? Differences from HTML4 differences/ Controversy p=5756620&N-s=1_679015&N-f=1_679015&N-fa=9820  Debate the-debate/1556  Infographic e1328040556991.jpeg  Ongoing _the_controversy_video_slides The next disruptive technology technology.html The debate matters vs-apps-why-the-debate-matters-and-who-will-win-2012-10
