Digital and web design have come a long way since the invention of the internet by Tim Berners-Lee
Although very much a modern day phenomenon it really took with the invention of the internet by Tim Berners-Lee in 1989. He founded the W3C consortium in 1994. (need to look at this a bit more)
There has been rapid growth and advancement since then with new technologies constantly being developed e.g. smartphones and apps. With widespread broadband where would we be without it?
Web design and development many principles are the same as in print but for screens. More recently the movement has been from static table design of 1990s to the start of CSS and not responsive and adaptive web design.
The User Experience (UX) and User Interface/Interaction (UI) has become much more important in recent years with many developers/designers pursuing this as a career path.
