It’s “March Madness!”
For those of you that have been feverishly watching the NCAA basketball tournament:

“March Madness” is a trademark! It happens to be registered by a holding company owned by the NCAA and a high school athletic association located in Illinois called March Madness Athletic Association, L.L.C. Apparently the Illinois High School Association has used the term since the 1930s!
“March is also a busy month for the lawyers in charge of enforcing [ ] trademarked properties, which include ‘March Madness,’ ‘Elite Eight’ and ‘Final Four.’ “
For more info on how the term gained its “dual use” then click here, or check out the Illinois High School Association v. GTE Vantage, Inc. , 99 F.3d 244(7th Cir. 1996) decision. For a few related Law Review articles:

The term “March Madness” also garnered dispute when a sports entertainment website owner was sued for trademark infringement. The ultimate issue was whether “March Madness” was a “generic term?” (See March Madness Athletics Ass’, v. Netfire, 310 F.Supp. 2d 786 (N.D. Tex. 2003)). For a summary of the case click here.
