Ratings are based on conversations with readers and audiences and are updated on an ongoing basis. An “A” rating means that the trend has continued to accelerate and impact how people and organizations think. A “B” rating indicates that the trend did not accelerate as planned but still has relevance. A “C” is given to trends that were too narrow in scope and did not continue to accelerate as planned. So far, we don’t believe any trends have warranted a “D” or “F” rating!
