created.
(vii) Use of rich media or creation of rich Internet applications (RIA) which provide for a more 
immersive, interactive experience. These may be integrated into web browsers or may be 
separate applications like that downloaded for Second Life (
www.secondlife.com
).
(viii) Rapid application development using interactive technology approaches known as 
‘Ajax’ (Asynchronous JavaScript and XML). The best- known Ajax implementation is 
Google Maps which is responsive since it does not require refreshes to display maps.
Figure 1.10 summarises the evolution of digital and web- related technologies. Note that the 
terms Web 2.0, 3.0 and 4.0 are not terms commonly used today, yet it’s useful to understand 
the principles of Web 2.0 in particular since they are important to creating interactive, inte-
grated desktop and mobile experiences (as explained in Chapter 11). Many sites still don’t 
have these characteristics.
