SAN FRANCISCO (AP) — The internet wouldn't be the same without the Like button, the thumbs-up icon that Facebook and other online services turned into digital catnip. Like it or not, the button has served as a creative catalyst, a dopamine delivery system and an emotional battering ram. It also became an international tourist attraction after Facebook plastered the symbol on a giant sign on that stood outside its Silicon Valley headquarters until the company rebranded itself as Meta Platforms in 2021.
