Trademark Infringement

I like the dusty, arid battles that occur over the use of registered, trademark slogans that nevertheless enter common use:

The Las Vegas Convention and Visitors Authority hasn't been too happy about companies and organizations that have attempted to profit or call attention to themselves by using some form of the phrase "What happens here, stays here," which it considers to be a registered trademark.

Now the basketball sneaker is on the other foot, and it's the National Collegiate Athletic Association that is riled up about the LVCVA's use of the term "March Madness."
