A few years back, I heard of a character called Hannah Montana from one of my nieces who desperately wanted her album. I couldn't be bothered going out to buy it, so I simply gave her money so she could do it herself. Sitting in the car, she sang songs from Hannah Montana, mimicking her teenage idol.

All fairly harmless stuff - after all, Hannah Montana was a Disney brand, wholesome and pure that teenage girls the world-over could relate to.

Then something happened. She grew up. From teen idol to woman and that's where it all began.

Like Madonna before her, and Kylie Minogue for that matter, Miley Cyrus, the former sweet teenage girl that played Hannah Montana wanted to evolve her brand image and take it to the next level. If she would have kept up the wholesome image, it probably would have ensured that her brand diminish over time. Instead, she reinvented her brand. First it started with a number of selfies in proactive poses creating headlines. Then it was the picture of her smoking pot which  I would imagine was not by accident - instead just part of a brand evolution.
