Today, it would be impossible to spend any significant amount of time online without running across a plethora of websites willing to deliver weekly (or even daily) email newsletters. And there is nothing wrong with this. There is an abundance of great digital content and plenty of people looking to consume as much as they can of it.
At the same time, I can't help but postulate that for every organization who successfully generates and delivers compelling content daily or weekly and has an engaged following, there are many others failing to keep up. For these organizations, I wonder if Franklin D. Roosevelt's "fireside chats" could serve as a great model for how they should communicate and engage with their audiences.
FDR delivered thirty fireside chats between 1933 and 1944. These chats, if you're not familiar, were 15- to 45-minute radio broadcasts in which President Roosevelt addressed the nation, mostly covering economic topics during the Great Depression and military topics throughout World War II.
Roosevelt never did more than four fireside chats in a single year; in fact, he delivered just one in both 1935 and 1939. Overall, he averaged one address about every five months over their 11-year run.
