Web 1.0 was dial-up, 50K average bandwidth, Web 2.0 is an average 1 megabit

of bandwidth and Web 3.0 will be 10 megabits of bandwidth all the time, which

will be the full video Web, and that will feel like Web 3.0.

- Reed Hastings, Founder and CEO of Netflix, at Technet Summit, Nov 2006

Software › Versions are substantial improvements over previous ones

› previous versions are withdrawn

Web 2.0› represents technological refinement and a remarkable leap in the

usage and functionality of the Web

› but not a significant technological revamp of an earlier Web, nor has it replaced Web 1.0

› an innovative and marketable catch-phrase, just as the underlying technology

In retrospect - Web 1.0› the success of Web 2.0, which started around 2001

› the era of the web prior to the dot-com bubble burst came to be identified as Web 1.0

The technologies of Web 2.0 were available prior to this period and Web 1.0 still forms a significant part of the Web

The first web pages and browsers appeared around 1993

This new medium grew faster than ever before, growing by almost 500,000% in less than 4 years

Web 1.0 technology and design elements:› Largely static webpages

› Use of framesets and guestbooks

› HTML and CSS

Disintermediation – a term coined by Amazon was the buzzword, as every one tried to get rid of middle men. It did not always work, as Levi’s found out

Hundreds of thousands of companies flocked to the internet adding

an e- to their names –termed by one author as Prefix Investing

But all of these were not profitable as a survey in late 2000 listed 21

firms with sales growth between 100-500% and red bottom lines

The bubble kept on growing,

aided by plenty of freely

available venture capital,

rapidly increasing stock prices,

market confidence of future

profits and a let down of

traditional guards like P/E ratios

On March 10, 2000 the curve

crashed and the bubble had

burst

From early 200 to 2002, more

than 500 internet firms shut down

Dale Dougherty of O’Reilly Media gave the name Web 2.0 to

a conference they were organising on more effective ways

to use the web› The term stuck and people carried it beyond its initial purpose, with

numerous definitions floating around on the net

A year later, Tim O’Reilly, CEO of O’Reilly Media came up

with a 5-page definition of Web 2.0 filled with tons of jargon

but his short message was that Web 2.0 refers to people

making connections with other people through the web

Social networking

Blogs and Microblogs

Knowledge contribution

Information and media sharing

User as contributor – Amazon reviews, eBay reputations

Architecture of participation: Blogs

Rich user experience: Gmail, Google

maps and AJAX

Radical trust: Wikipedia

Customer self service: Google

AdSense

Technological refinements Consumer Behaviour

Broadband Privacy

Browser wars Greater reliance on technology

Ajax Contributory role

Flash, Java Increased Socialising

Widgetisation Alternative source of entertainment

Services, not packaged software, with cost-

effective scalability: SaaS

Control over unique, hard-to-recreate data sources

that get richer as more people use them – issues of

anti-trust, monopoly, Google Books, Netscape

Trusting users as co-developers, save on operating

expenses

Although the term suggests a new version of the www, it does not refer to an update to any technical specifications

2.0 refers to cumulative changes in the ways developers and end-users use the Web

Whether Web 2.0 is qualitatively different from prior web technologies has been challenged by World Wide Web inventor Tim Berners Lee who called the term a piece of jargon. › “Web 1.0 was all about connecting people. It was an interactive

space, and I think Web 2.0 is, of course, a piece of jargon, nobody even knows what it means. If Web 2.0 for you is blogs and wikis, then that is people to people. But that was what the Web was supposed to be all along. And in fact, you know, this Web 2.0, quote, it means using the standards which have been produced by all these people working on Web 1.0. It means using the document object model, it means for HTML and SVG, and so on. It's using HTTP, so it's building stuff using the Web standards, plus JavaScript, of course.”

2.0 or 1.0, fact remains that the way we use the web has certainly changed dramatically in the last decade, empowering the user not just as a consumer but as a producer as well, removing information

asymmetries and catalysing globalisation

Answering concrete questions instead of

searching for keywords

› Semantic Web

› OWL (Web Ontology Language)

Ubiquitous Computing and linkage of

different semantic services

› Example: On-bord computer in cars could

combine GPS and semantic software to find gas

stations

Increasing emphasis on user engagement

“ My prediction would be that Web 3.0 will ultimately be seen as applications which are pieced together. There is a number of characteristics: the applications are relatively small, the data is in the cloud, the applications can run on any device, PC or mobile phone, the applications are very fast and customizable. Furthermore, the applications are distributed virtually: literally by social networks, by email. You won`t get to the store and purchase them… That`s a very different application model than we`ve ever seen in computing“ ERIC SCHMIDT, CEO of Google
