The planners started as simply Franklin, and Covey wrote his book. At some later time, when Covey had become really famous for his book and had somewhat of a media empire surrounding "The 7 Habits" he and Franklin merged to create Franklin Covey, which is where the current generation of planners come from.

I never made it all the way through the book (I still have a copy if you had cared to read it), but I did find the discussion of proactiveness and paradigms useful. I think in the long run Covey is a victim of his own success: his concepts have so permeated the culture that now they seem unoriginal.
