Traditionally-print publications have a huge problem with linking to whatever they are talking about. I've seen articles about a video which don't link to the video the article is about.
Interestingly, this is often because writers are not allowed to add links. Links are the domain of the editors, which is a separate union.
Blogs get around this by not being published "articles", so the author can add their own linking. This is one reason why "blogs" are called out so explicitly on news websites.
