HTML5 is the latest version of HTML that introduces new features like video, audio, and geolocation. It is still being developed with the goal of improving multimedia support while keeping HTML easily readable. HTML5 adds capabilities that allow more functionality within browsers rather than requiring external plugins. It also allows for mobile web apps as an alternative to native apps. While HTML5 adoption is growing, a debate continues around how it compares to native apps and other technologies like Flash.

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.  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.  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.  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.  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.  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
