Content Producer? I know "Content Management" is a big deal today, but content would be defined as a lot of shared resources. Writings, poetry, music, books, documents, records.
Because content can be so much easier shared does not take away the professionalism from writers, movie producers, musicians or photographers.
What it really means is every day people are much more free to add content for sharing with others. It is true that some content is better quality and more professional, but the way you describe it is like our local news stations asking viewers to send in their photo's to be used on the air and no longer relying on freelancers for compensation. That still does not diminish their need for professionals to handle the real work!
In my opinion you just watered down the entire industry by blaming 'content'.
My current job title is "Content Manager" I find it somewhat unique. Creating photographs is just one aspect of my job. It also includes training, shared resources, documentation, design, SharePoint etc.
You might be quite shocked what I make per year doing this.
