Publishers need to invest in revenue innovation

Publishers face a lot of challenges these days. One of the big ones is engagement. Some recent studies give important insights into how to engage readers, and I summarize them briefly.

But publishers also need to find new ways to make money.

Jim McKelvey recently explained the way they're monetizing content on his Invisibly app. It's very interesting, but publishers need a lot more options.

My question to publishers is this: How are you working to innovate your revenue sources?
