Advertisements and billboards often end up in inviting controversies and criticisms as the companies go in great lengths to attract consumer attention to their products and ideas.

At times, the advertisement campaigns go beyond the normal product showcase to ignite the shock factor among the audience to convey the message.

The campaign has invited widespread reactions forcing the company to withdraw the advertisement featuring Pope Benedict XVI and an imam kissing each other on the mouth.

Similarly, a channel 4 advert for its second TV series My Big Fat Gypsy Wedding invited more than 500 petitions regarding the words used in the campaign.
