The document discusses a CMOST campaign for a chalk flash mob event that was not as successful as intended. It analyzes what social media channels worked best (Facebook, Instagram, YouTube), what channels did not work (Pinterest, Doodly), and identifies mistakes like using too many channels, not planning far enough in advance, and not securing influencers to promote the event. Recommendations include starting promotion earlier, focusing efforts on fewer dominant channels, and involving a local sports team to gain more attention.
