She was an under-30. No idea how she knew what tupperware was. Maybe it's turned into a generic name for 'plastic food container'(?)

As far as market domination, you're probably right, I never really paid attention. I have to wonder if it was that they already had a decent line of SLRs and lenses for 35mm. I didn't buy one as they didn't fit my hands like the Nikons (possibly dumb reason but I was coming from Exactas).
