In 1917 Colgate came to India and said "why do you guys still use salt and charcoal to clean ur teeth, use our paste!!".
Now in 2015, Colgate is advertising asking "does ur toothpaste have salt in it?" And goes on to say "our brush is coated with charcoal which is GooD for white teeth".
It took them 95+years to know that.
But we will never realise our GooD old values
