Certainly, product categories such as refrigerators or even smartphones have achieved even deeper penetration, but looking at single companies, it's a short list with probable names such as GE (light bulbs) or 3M (Scotch tape).
The maker of Scotch-brand tape was sued by a competitor who accused 3M (nyse: MMM - news - people ) of using price rebates to break into the market for private-label tape.
When combined with 3M's Dual Brightness Enhancement Film (DBEF), Uniformity Tape allows display manufacturers even more design freedom to innovate and use less LEDs to create a backlight that not only meets energy standards, but also remains competitive at a low cost.
