This post is part of my series featuring established companies and the smaller, more aggressive or innovative rivals that may eventually succeed them.

"From sea to shining sea" aptly describes the distance between Nike (NYSE: NKE) and Under Armour (NYSE: UA). Nike is headquartered in Beaverton, Oregon, while Under Armour calls Baltimore, Maryland, home. Nike splashed onto the scene locally in Oregon in 1964 and has developed a true international brand. With the likes of Michael Jordan, Joan Benoit Samuelson and Tiger Woods serving as spokesmen for the company, Nike has transcended virtually every sport and every demographic group.

Under Armour, founded in 1995, at first appealed to the serious athlete with its moisture-wicking synthetic fibers that help keep sweat and moisture from the skin and help regulate body temperature during strenuous exercise. Under Armour then discovered it was unwittingly creating a fashion statement. Like Nike, Under Armour is also crossing over to various demographic groups and weekend warriors as well.

Nike has the famous Swish as its corporate logo, while Under Armour has branded the bold U over A insignia. Nike has established its brand globally with a dual strategy of major retailers selling its apparel and shoes and its own distribution system. Nike has over 250 NikeTown stores in the United States and over 230 internationally. With the retail store system Nike can control the entire purchase from apparel to shoes to socks to sweatbands. Under Armour has just begun its own retail stores with two prototypes, one in Maryland and one in Illinois. It sells its various products through multiple channels, including its own user-friendly e-commerce web site.
