Some of my biggest gains have come from tracing powerful growth trends back to the source.
If lemonade sales are booming, then I want to know who's supplying the lemons.
The smartphone revolution, for instance, has been very good to Apple (Nasdaq: AAPL). And analysts are forecasting a 27% increase in smartphone sales next year - or 868 million phones sold.
Of course, smartphone producers aren't the only businesses seeing increased revenue from this technological revolution.
And I'm not just talking about mobile phones, but also tablets, PC monitors and LCD TVs.
What do these products all have in common? Glass display screens.
There are only a couple of major glass manufacturers vying for a piece of this lucrative market. But only one has set the standard.
This industry leader has a screen that offers brilliant resolution as well as extreme durability and scratch resistance.
The company, Corning Inc. (NYSE: GLW), has a long history as an industry innovator.
In 1947, Corning invented the process to mass-produce glass picture tubes, making TV sets affordable for the public. The following year, 1 million sets were sold in the United States.
The company began mass-producing tubes for color TV in 1953.
Just six years later, Corning invented the fusion process, creating glass that is exceptionally flat, clean and well-suited to the exacting requirements of liquid crystal displays.
And after 160 years in business, the company still leads the industry in innovation.
Corning's newest advance is called Gorilla Glass, an ultra-thin and highly sensitive (important for touch-screen applications) type of glass for smartphones and other devices. To boot, it is extremely strong and nearly impervious to normal wear and tear.
Just about every major manufacturer finds this rare combination of attributes highly attractive. And that's why you'll find Gorilla Glass on 33 brands spanning 900 models worldwide.
If you own a Sony Bravia TV, a Samsung Galaxy tablet, a Dell laptop computer or a Motorola DROID phone, then you've come in contact with this specialty glass.
All told, Gorilla Glass has been installed in more than 1 billion devices around the world.
