History Clips Only on Instagram: "In the 1980s, fast food advertising became unexpectedly competitive on television. One McDonald’s commercial showed children favoring a rival burger, blurring brand loyalty in a subtle but powerful way. What seemed harmless quickly crossed corporate lines, revealing how closely companies guarded public perception during the golden age of television advertising.
