A survey commissioned by Fox itself claimed that 10 out of 10 respondents liked the new puck. In 2014, sportswriter Aaron Brown of Slate called it "one of sports broadcasting’s most-ridiculed experiments." Cavallaro defended FoxTrax in a 1997 paper for IEEE Computer Graphics and Applications, calling it an "overall success" that contributed to higher ratings for Fox. "While we certainly had moments of doubt, the Puck Truck proved successful at every event it attended," he wrote. "It's true that some fans don't care for the effect, but many think it's an improvement." He later claimed that "most people were impressed by the technology even if they hated the effect." Building upon his work, Cavallaro co-established a new company known as Sportvision in 1998, which marketed other forms of sports graphics technologies, including virtual down lines for football. As part of a larger project with SAP and Sportvision, the NHL had since experimented with player and puck tracking using embedded microchips. The new system's capabilities were demonstrated on-air during the 2019 NHL All-Star Game. The NHL planned to deploy tracking at all arenas for the 2019–20 season, however this was delayed to at least the 2020–21 due to a change in technology provider.
