So they couldn't even take orders for it when the calls hit them.
The intention of the phone-bombing was that the stores would order a bunch of boxes each, of KPT, so that they hit the shelves.
KPT was one of those things that as a Photoshop user, you just had to have in your toolbox at the time.
I.e. even if you just did boring graphics design or classic compositing, there was always a moment when some filter from the plugin would come in handy.
After that KPT hit a critical installed base. I.e. word of mouth and piracy did the rest as far as marketing goes.
Shelve space for software was auctioned-off at the time. Microsoft was number one in buying shelve space ofc.
The closer to the entrance of a shop (or the software area of a department store) and the higher up the shelve your boxes would end up, the more you had to pay.
Now KPT wasn't on any shelve anywhere at all when Uwe pulled this one off.
That changed after.
