Apps are not Applications

Understanding the new world of apps. Apps are not Applications.

That should have been the first sign that the software market was changing. It’s obvious in retrospect; people were buying software that would make them laugh. This runs counter to the common understanding of an Application. An Application represents the developer’s best effort at creating software that applies the capabilities of the device to solving a specific problem. Making people laugh is not a problem an Application can solve; it’s not about the device it’s about the person using it.
