In a truly galaxy-brained rebrand, Microsoft Office is now the ‘Microsoft 365 Copilot app,’ but Copilot is also still the name of the AI assistant

About a decade ago, hardware company Corsair attempted to pivot from its classic logo—a subtle trio of ship sails—to a newer, edgier look, a pair of crossed swords that gave off regrettable ‘2000s tribal tattoo’ energy. The rebrand didn’t last long: after a fierce outcry from people who correctly thought the new logo sucked, Corsair swapped to a refreshed take on the sail logo, which it’s been using ever since.

Corsair was established in 1994, and made about $1.4 billion last year—which I bring up because today Microsoft, a slightly bigger company, has slipped on its own rebranding banana peel. The company is seemingly all but ditching the Office name—which it introduced four years before Corsair existed, and which drove more than $30 billion in revenue just last quarter—with a catchy new name: “Microsoft 365 Copilot app.”
