Animation has evolved from simple optical illusions to a complex art form. Early techniques like zoetropes and flip books paved the way for cel animation and rotoscoping. Pioneers like Walt Disney and Winsor McCay pushed the boundaries, leading to the Golden Age of Animation. Modern 2D animation blends traditional techniques with digital tools. Studios worldwide have developed unique styles, from Japanese anime to French artistic films. Today, 2D animation thrives in TV shows, web series, and independent projects, embracing both limited animation and cutting-edge software.
