Still, such a tough challenge may inspire brands to find a truly great solution—and it has been the case with Post-it notes, owned by the 3M Company, which launched a new US campaign under the “Go ahead” tagline. The new multi-platform promotion, which was devised and developed by Grey New York, plays around the totally new approach to advertising the iconic notes. Now, they are much more than just bright sticky pieces of paper for writing reminders on—they are tools for the self-expression.

The score of each of the brands was calculated by subtracting negative feedback from positive feedback. View some highlights from the research below.

The brand, which last year celebrated its 30th anniversary in the USA, will feature the 23-year old lady in its multi-platform campaign, which is expected to include more than just adverts. According to Ad Age, “executives close to the company noted she will not be involved in the company’s Super Bowl campaign.” Apparently, it’s because the young celebrity, who is gaining her power quite fast in the entertainment business, currently doesn’t have the superstar presence of such performers as Beyonce, who has been tapped by Pepsi and will be headlining the Super Bowl halftime show sponsored by the brand.

Coca-Cola US is piloting vending machines, which accept payments made via a mobile device —the new initiative was launched through the company’s partnership with the Isis joint venture created by AT&T Mobility, T-Mobile USA and Verizon Wireless.  The iconic beverages giant is not the first one which provides its consumers with such an opportunity (for instance, Starbucks offered it in 2011), but it is still a great move for the company.
