I’d thought the Content is King debate was over, but I saw it rearing its jester’s head once again recently. Argh!
“Content is King” is a phrase that seems to have come out of content marketing to express the simple idea that content is now the most important form of marketing. Which is actually a rather weird and restricted meaning of the word content, since it was meant to contrast with traditional advertising which is, after all, content.
What I think those who coined the term were really trying to say is that in marketing content that informs now performs better than content that attempts to persuade. This is a direct result of content being easier to get on the Web, which means that readers can get the information they want while avoiding any overt attempt to persuade them.
