Apple came up with an elegant way to contain applications in their operating system.

The challenge was to design a structure that would allow an application to remain self-contained while surviving on a file system that didn't believe in cheapening its architecture with proprietary workarounds. The answer came from an older ancestor of Mac OS X named NeXT, which treated an application as a bundle represented within a directory. The bundle concept introduces an approach to group application resources, binaries, and other related files.
