Baltimore

Under Armour is nipping at Nike's heels in apparel sales. Now, with its latest product, unveiled at the Consumer Electronics Show (CES) on Tuesday, the Baltimore company is going after Nike on another front. UA Record, Under Armour's new health-tracking software, pairs with a bevy of wearable devices. Its dashboard allows the fitness obsessed to interact with others by sharing results and posting photos and videos. "It's a social network for activity," said Senior Vice President Robin Thurston on the CES show floor where the company claimed a central space.

Amazon.com announced yesterday that it will be expanding its same-day delivery service in six metro areas: New York City, Washington, D.C., Philadelphia, Baltimore, Dallas and Indianapolis. Customers in those cities will be able to have their orders delivered on the same day if they purchase before noon — for a fee, of course. The question remains, however, is same-day shipping worth it?

Amazon.com has been testing the use of its own delivery vehicles in Los Angeles, New York City and San Francisco following an earlier pilot in the U.K. Does Amazon's move mean it will compete with UPS and FedEx and become a third private player in the U.S. parcel delivery market? Certainly it will have an impact and could begin to manage inventory, fulfillment and delivery for other consumer products businesses.

Under Armour is working to stretch the boundaries of a sportswear maker by branching into tech gadgets and lifestyle accessories. But there are limitations on the Baltimore company's innovations when other companies beat them to the patent. One of Under Armour's newest products became a recent victim of a patent infringement lawsuit
