The Null Device
Ever wonder why Google have a copyright notice at the bottom of their (not exactly intellectual-property-rich) search page? It's not so much to appease the lawyers as it is to let you know where the page ends:
In its early days, the company asked some focus group participants to search for information using its site. But many people, when they went to Google, did nothing for a minute or two. When asked why, these apparent procrastinators said they were waiting for the rest of the site to load. So, the company thought that by putting a copyright notice on its page--something usually found only at the bottom of a fully loaded page--perhaps people would get the hint that the spartan page was fully loaded.
