The Zenith Space Command, one of the first wireless television remotes, featured an influential and durable clicky button, pioneering a simplicity of form that has since been abandoned.

The remote used mechanical engineering with a spring-loaded hammer and solid aluminum rod to emit high-frequency tones that triggered commands in the television.

Modern remotes have become complicated and cluttered, but streaming devices like Roku have brought back a minimalist aesthetic with essential buttons.
