Flash, like Java, was not initially developed with the Internet in mind; although, both are designed to run efficiently on multiple platforms. But unlike Java it has at its core a vector graphics engine.
With this in mind we could say that Flash from the ground up is designed for distribution over the Web.
Vector graphics, programmer controlled component distribution, built-in streaming of quality sound, and now high-quality video uniquely position Flash to play a significant role in the future of the Web.
