What texts are educational?

There are vast amounts of texts (multimedia) that are available to todays world. With that in mind, it is a good thing to take a moment to anylize what may or may not be educational text. Although many media are entertaining, they are also educational on different levels.
One example would be is, I would define most news media to be educational. Some may seem to be biased, but their general purpose is to inform the audiance of events that have happened recently, or of upcoming events, both of which may have or have had an impact on our (the public) lives.
Historical books and television programs, many children's shows, weather reports, advertisements, etc. come to us to inform, teach, or expand on what is known. These convey information to us through words, sounds, and images to intrigue our senses to pay attention to what they want to "tell" us. Some music is informative, even in the pop mainstream.
There are some text that come across as educational, but are actually nothing more than persuave arguements. Many advertisement companies want you to buy their product, so give a small amount of true information so that they can make you believe that they have the better solutions. This is NOT educational, yet looks a if it were.
Be aware of what you see, so that you know what you are swallowing.
