NBC has announced Simon has signed a multi-year deal to stay as a judge on America's Got Talent, although the number of years was not specified.
In addition, Simon -- who created the Got Talent franchise, which has aired local editions in 70 territories around the world -- will also continue to serve as executive producer of America's Got Talent.
"I want to thank NBC for their continued passion and belief for America's Got Talent over the past few years," Simon said in a statement.
"Without NBC, we wouldn't be making Got Talent and I'm very proud to work with them. Together, with a fantastic production team, we have been able to attract the best talent in the world. I'm very excited for the next few years."
America's Got Talent is currently airing its thirteenth season, with contestants heading into the semifinals. The reality talent competition series continues to be the top-ranked summer program for the network.
"Simon Cowell is an extraordinary showman whose success stories over the years on multiple continents speak for themselves," NBC reality chief Paul Telegdy said.
"We are thrilled that he will continue as a judge on America's Got Talent and that his stewardship of the franchise will go forward for many years to come."
As part of Simon's ongoing deal with NBC, he will also be a judge on the show's new America's Got Talent: The Champions spinoff when it airs on Monday nights in between NBC's Fall 2018 and Spring 2019 seasons of The Voice.
Trish Kinane, president of AGT's production company FremantleMedia North America, added that few people have impacted the world of entertainment as significantly as Simon.
"He knows what it takes to find and nurture talent, and he knows how to entertain an audience, creating enduring and much-loved formats. We look forward to continuing our creative partnership," Trish explained.
