Branded Bibles are the epitome of American capitalism in the modern age. The phenomenon has already gone from tragedy to farce. You cannot really blame the publishers. What better partner for a cross product promotion than God?
So allow me to coin this rule: whenever a concept gets its own branded Bible, that concept is officially mainstream in the American market.
The other night I saw that there is a now a "Green" Bible. It is an edition of the NRSV (of course) which is manufactured in an environmentally friendly way. A new notation system arrives in the form of the green letter edition ("verses and passages that speak to God’s care for creation highlighted in green").
Yes, "green" as a consumer philosophy has made it big time in America.
