Made known to the general public through newspapers, television, social media, or other media channels; advertised or promoted widely.
From 'publicize' (back-formation from 'publicity,' from French 'public' and Latin 'publicus'). The verb form became standard in the early 20th century as mass media expanded.
Before the internet, getting something 'publicized' required convincing newspaper editors or TV stations, but social media means anyone can publicize anything instantly—which is why checking sources became absolutely critical.
