How did streamline begin?

Streamline, as a concept, began in the early 20th century, primarily in the context of design and engineering, emphasizing efficiency and aerodynamics. The movement gained popularity with the advent of modernist design principles and was exemplified by the sleek, futuristic shapes of trains and automobiles. In a broader sense, the term "streamlining" has evolved to refer to processes and systems aimed at increasing efficiency and reducing waste across various industries. Today, it encompasses a range of practices from manufacturing to software development, focusing on optimizing workflows and enhancing productivity.
