Samoa Joe had the longest title reign to date when he held the belt for 21 months and four days. During his reign, ROH held a cross-promotional show with Frontier Wrestling Alliance in the United Kingdom on May 17, 2003, called Frontiers of Honor. At that show, Joe turned the title into the ROH World Championship when he defended it against The Zebra Kid. Since then the title has been defended in Germany, Canada, Switzerland, Austria, Mexico, Japan, Ireland, Italy, and Spain.
