The meaning of the word “content” has evolved over the last few years. It used to mean something that was contained, like the contents of a jar, or the chapters of a book. Now, content has the broader definition of being “a substance of significance.”
In the digital world, content is not only words (like this blog), but also images and videos. In fact, even something as abstract as an idea can be considered content.
The value of content is not defined by its container, but rather by its quality. True content can have many different containers, and the implementation and purpose of the content can change with each container.
