The most impressive pair of numbers (to me at least) in that article is 20 million rolls of Kodak film sold versus 1 million packs of TIP film. Note that Kodak kicked Ektachrome into the curb because it made only a tiny percentage of their overall film sales so chances are more TIP film packs were sold than rolls of Ektachrome. Remember that TIP can neither match the precious colors of Ektachrome nor does a TIP photo have the resolution and the many flexible options for use and post processing. And it's much more expensive than a roll of Ektachrome and has only 8 vs. 36 frames, too.
If Kodak couldn't sell more Ektachrome than TIP by a large factor, their strategy and marketing are abject failures, and blaming their demise on the "digital revolution" is nothing but a sleazy cover up for that.
