He noted Friday that Empire used the word "power" in advertising images.
"They didn't have to do that," Jackson said.
An Empire promotion features actors Terrence Howard and Taraji P. Henson with smoldering expressions, similar to a Power image of actors Omari Hardwick and Naturi Naughton.
After Jackson used his social media account to point out the similarities recently, Henson responded on Twitter: "I pay attention to $, not cents," adding a peace sign emoji.
"Can you say anything bad when a woman says something to you and not be inappropriate?" Jackson said. "So I just laughed about it and let it brush. That's cool. I think there's room for more actual television shows."
Both programs have primarily African-American casts, but they're thematically different: the connection to the music business is much more a part of the Fox series.
