Looks like mocking is the only way to dislodge your competition and/or prove that your advertising form is creative.
I recently saw this ad of Bajaj’s attempt to openly take a dig at its closest competitor Hero MotoCorp and was appalled at how the agency defines this a creative idea that is unique.
One, its definitely not unique as this is a beaten-to-death formula. Two, its defintely not creative and never will be. The closest you can get is grab a few eye-balls (and remember you are doing this for your competitor for free). Chances are you will help the competitor’s brand to get registered.
Side Note: You can get more creative and innovative by aping (and not mocking).
