Kodak had a number of key patents on CCD imagers. They had a fab (that still exists) turning out high resolution linear and area array sensors for special applications and DSLRs. Much of the commercial satellite imagery seen on Google maps comes via Kodak sensors.

Kodak's problem is that they always bottom fed the market with their film cameras and retained the same position in digicams. The former strategy is great when you want to drive demand for consumables. It doesn't work when there is nothing to consume in the picture taking process.
