Title Bout Championship Boxing is the latest rendition of a professional boxing simulation that dates back to the highly successful and current cult classic board game, Title Bout: The Game of Professional Boxing, produced by Avalon Hill Game Company.

In 1976 Jim and Tom Trunzo began selling their board game boxing simulation, under the auspices of Jim Barnes' Statis-Pro Games, a humble effort simply called Professional Boxing debuted with fifty rated heavyweights. Enough interest was shown in the neophyte product to encourage the 1977 release of a mail order product entitled Truco Championship Boxing, which contained over 200 rated fighters from boxing's eight main divisions.

However, the first major step in the boxing simulation came when Avalon Hill decided to launch a line of sports games to complement its prestigious line of war board games. Produced and marketed by Avalon Hill under the Sports Illustrated banner, Title Bout: The Game of Championship Boxing went on sell in 1979. The release of the Avalon Hill game resulted in both critical acclaim and tens of thousands of sells. The Title Bout board game remained a solid seller for most of its twelve year run with Avalon Hill.

In 1991, with board games giving way to computer games, Avalon Hill began to do a major restructuring of their business and decided to cutback and attempt a return to their war game roots and pursue a broader market by producing family-oriented games. The rights to Title Bout reverted to Jim and Tom Trunzo, who promptly entered into an agreement with Lance Haffner Games and converted the Title Bout board game into a DOS computer product called TKO Pro Boxing. The relationship with Lance Haffner Games was again, quite profitable and commercially successful for a period of four years.

By 1995, DOS products were basically obsolete and the Trunzo's amicably ended their relationship with Lance Haffner Games and embarked on their own attempt to market their product via their own company Comp-U-Sports. Title Fight Pro Boxing, a Windows-based and improved version of TKO Pro Boxing, entered the market in 1996 and became a finalist in Computer Gaming World's "Sports Game of the Year" competition. Considering that Title Fight was the result of a three-man effort (the brothers and a single programmer) and was competing against major companies like Electronic Arts and Sierra-Online, making it to the finals was a tremendous achievement.

Two years later Comp-U-Sports hooked their wagon to what they believed would be a shooting star by entering into an agreement with one of the major players in sports simulations, APBA. In 1979, APBA released both a computer version and a board game version of the Trunzo's boxing simulation, APBA Pro Boxing. Unfortunately for all involved, APBA over-extended itself and within eighteen months, declared bankruptcy via Chapter 11. In a pre-trial settlement, the Trunzo's exchanged significant unpaid royalties for the game rights to their boxing simulation.

Comp-U-Sports picked up where it had left off in 1995 and continued to product updated versions of its product, selling it via the Internet, for the most part. In 2001, the last significant version of the computer boxing simulation manifested itself on CD-ROM, Title Fight 2001. That product, which sold almost 2000 copies in a little over a year, brought about the current relationship between Comp-U-Sports and Out of the Park Developments, which will produce and market the most sophisticated and ambitious version of the game yet, Title Bout Championship Boxing.
