There's often a lag between the time something new comes along and the time it is fully incorporated into our lives or work. When websites first came online, in the mid-'90s, they had obvious potential but companies weren't sure what to do with them. As I recall, many of them focused on the history of the company, stocks and market activity, and various other things useless to most visitors. The content was what the company owner thought was interesting; it was not what the prospective customers needed.
At the time, there wasn't much in the way of instruction for web designers and there were few rules about how to make a website work or what it should be. An architecture firm in my area had a beautiful website, graced by one the firm's most impressive projects. The problem was, it took forever to load. I analyzed the code and the files, and discovered they were using a huge image file. They apparently didn't know that there usually is no discernible difference between an image file of a few kilobytes and the same image in a two-megabyte file.
