Yep. A good example is home video. First came Beta and then it was beaten out by VHS because the VHS tape was long enough for someone to record up to 6 or 8 hrs of video even though Beta was a sharper picture (or so I've heard). Then along comes DVD and beats out VHS because of it having a sharper picture and not being prone to having the media destroyed if the machine goes haywire. Now they're bringing out the Blu-Ray disk which is is an even sharper picture. Likewise computers started out with CRT monitors and now most everyone uses an LCD monitor instead. Technology is always evolving as new things are discovered. Books also have evolved over the centuries. First it was clay tablets, then papyrus scrolls, then hand written books, then printed books and now we have the e-book.
