Intel launched Centrino in 2003 as a branding platform for thin, wireless laptops, and its advertising carried the company's familiar four-note audio logo. As those laptops became common in homes, schools and offices, the chime became shorthand for a new computer starting up or a technology product being introduced. Soundboard users later lifted the short clip for memes and edits, where it now works as a nostalgic signal for anything tech-related, from fake adverts to jokes about old hardware still running today.
