You might be surprised.It's not quite at that level, but there is a fair amount of product put out each year from Paizo - even more if you count the Pathfinder Society adventure downloads. (At its peak, TSR had an insane amount of product per month).
TSR's output peaked at 79 game products in 1995.
Paizo's output for 2013 (excluding miniatures, novels, Pathfinder Society releases and the card game) included 12 adventure paths, 12 campaign setting supplements, 14 companion products, 6 adventures, 15 map products, 10 packs of cards, 5 sets of pawns, and 5 hardcovers and misc. accessories. That's a total of... wait for it... 79 products.
