It has often been said in filmic terms that if a story can’t be told in 90 minutes than it’s not worth telling. Try telling that to The Godfather.
However this certainly rings true on some level, especially in advertising where you’re engaging with a customer or selling a product rather than telling a sprawling, expansive story of gun violence and enemy disposal.
Who does benefit from the longer format? For a customer it’s good to keep things brief, nobody needs to sit through another colossal Thomson marathon, but conversely six second Vines may seem too short for the purpose.
Six seconds may be the prime length for our fleeting attention spans, but for marketing, this truncated length can be too much of a handicap to get a brand message across.
