Media on the net, and www is it?

As I recall, the world wide web was conceived as a hypertext base.
those. clicking on which thread the term / word in the text we ideally place on its definition.

For example rbc.ru.

I read the news "The mayor of Arkhangelsk posted compromising material on the governor on the website of the mayor's office" (http://top.rbc.ru/incidents/12/07/2007/109013.shtml).
It is surprising that, in the text itself, I did not see any links to the website of the mayor’s office itself, or to the video clip of course. I had to do all this through Yandex.

Kaspersky Lab attacked a Chinese competitor (http://www.cnews.ru/news/top/index.shtml?2007/07/12/258590).
There are no links to either Kaspersky or Chinese competitors.
