Actually, this became an issue just at the end of the 1990s. In the first years professional websites were usually designed and made by dedicated screen designers. Edit: Usually, it was also the same person who was responsible for the design and who made the basic layout templets, meaning this person also understood the technical basics, which in turn allowed for some amazing creativity. (The standard expectation was that the [re]launch of a major page would add to the language and definition of the media in some way.) It was really more at the height of the dot.com-bubble that things became more standard and conventional designers took over.
