Interesting piece in today's WSJ entitled "Seeking Fame in Apple's Sea of Apps."

The article notes that Apple gets 30% of any third-party app sales, and that as of today customers had downloaded more than 1.5 billion free and paid apps.

But most revealing was this tale of trademark infringement:

Some developers try to capitalize on popular brands by embedding those brand names into their own apps' descriptions. For example, a recent search for EA, the brand for game giant Electronic Arts Inc., turned up 15 games from a company called Digital Chocolate Inc. A close look at the games' description showed that the word "each" was abbreviated to "ea." Digital Chocolate Chief Executive Trip Hawkins was a co-founder of EA.

An EA spokesman called the tactic "barnacle marketing." On Monday, Digital Chocolate stopped using the abbreviation.
