Back in 1996, in the early days of the World Wide Web and when the Blue Letter Bible first came out, hyperlinks were pretty much always blue in color. Our vision was, and still is, to develop free Bible study software where the Bible is the center of the experience with study resources that link off of every word in the Bible. With hundreds of thousands of links that were all blue, we decided to call it the Blue Letter Bible as a play on the more commonly referenced red-letter editions of Scripture.
The name Blue Letter Bible has endured, and is a constant reminder to us all to make the Bible the center of our study.
