However, upon looking at the page describing the goals of this newspaper, you discover it is published by a group of individuals that advocate the segregation of the white and black races. Thus, the article you read could be suspect based on the extreme position of the sponsoring group. The intent of advertising is to sell a product or idea. Sometimes advertising is woven into an article, where it is hard to notice that the information presented is actually part of an advertisement. An example in the print world would be a multi-page, special advertising insert in Newsweek, paid for by a leading group of pharmaceutical companies that discusses new developments in drug treatments for arthritis.
Some information is very time sensitive.
For example, a page talking about the top rate Web search engines in 1997 is going to be horribly out of date in 2000. There have been incredible changes in search engine technology and new developments appear almost monthly. However, a page discussing the Civil War is likely still relevant today even if the page was created in 1996 and has not been updated. Regardless, a site should always provide some indication of when the information was created or the site was last updated. Coverage is one of the most important factors to consider before using the information in a Web page.
