Step Two: Prepare to brainstorm
Gather tag lines from other companies and brands.Look in other categories besides your own and try to find tag lines from both large and small companies.
As you find tag lines, write them on index cards or individual slips of paper.You will be mixing and matching them and pairing them with unrelated items as you brainstorm.
Pay attention to the words used, how they are put together, and which of the above questions they address.
By doing this, you are more likely to come up with a unique angle for your own tag line.
