When Transformers first debuted in 1985, it was one of many animated series designed specifically to sell toys. The series was a hit, in large part because of the voice of Optimus Prime as created by Peter Cullen. In 2023, Peter Cullen was given an Emmy for Lifetime Achievement in Children's and Family Programming, proving that Optimus Prime and the Transformers' legacy is about much more than simply selling robot toys. In 2007, the Michael Bay-directed Transformers debuted in theaters, and the first time Optimus Prime spoke in Peter Cullen's voice, audiences cheered. It was a direct emotional connection to childhood for older fans.
