Put these cameras in order of their invention: Polaroid, Brownie, Digital.

The correct chronological order of the invention of these cameras is Brownie, Polaroid, and Digital.

The Kodak Brownie, introduced in 1900, was one of the first cameras that made photography accessible to the general public, primarily due to its low cost and the simplicity of use. This marked the democratization of photography, allowing everyday people to take snapshots without requiring extensive knowledge of photographic techniques.

Following this, Polaroid cameras, which introduced instant photography, began to emerge in the late 1940s. The first commercial instant camera was the Polaroid Model 95, released in 1948. This innovation allowed photographers to produce developed images within minutes after capturing a shot, revolutionizing how people interacted with photography.

Digital cameras began to appear in the late 20th century, with the first models developed in the 1980s. Over the following decades, digital technology advanced significantly, leading to the decline of film cameras and the eventual dominance of digital photography in the 21st century.

Therefore, the order of invention highlights the evolution of photography technology: starting with the Brownie camera, then moving to instant photography with Polaroid, and concluding with the rise of digital cameras.
