The Daily Telegraph reported Friday that digital technology has allowed the late Beatles star to become a TV pitchman for the charity One Laptop per Child.
"Imagine every child no matter where in the world they were could access a universe of knowledge," Lennon is show saying in the commercial, an apparent reference to his solo hit "Imagine."
"They would have a chance to learn, to dream, to achieve anything they want.
"I tried to do it through my music, but now you can do it in a very different way."
Lennon's appearance in the commercial was approved by his widow, singer Yoko Ono, the British newspaper said.
Lennon was shot and killed in New York by a fan on Dec. 8, 1980.
