The syndicated TV series "On-Air with Ryan Seacrest" (search) is going off the air, permanently.

Seacrest was unable to turn his visibility as host of Fox's "American Idol" (search) into success for the talk and music show, and low ratings led Twentieth Television on Tuesday to announce the end of production.

"I am proud of my team who worked tirelessly every day," Seacrest said in a statement. "I wouldn't have changed anything about this entire experience and I look forward to building my business within Twentieth Television."

The Fox TV-owned studio said it believed the goal of providing viewers with "an engaging and alternative source of entertainment" was accomplished.

"It was our desire that the program would appeal to a wide array of viewers but, unfortunately, the marketplace's response was not as strong as we had hoped," the studio said in a statement. "On-Air," which debuted in January from a studio in the complex where the Academy Awards (search) are held, will be broadcast through Sept. 17.

Seacrest will remain with "American Idol," the hit talent-search series which returns for its fourth season in January. He'll also keep his day job as host of the Los Angeles radio show, "On-Air with Ryan Seacrest," and with the weekly countdown show "American Top 40."

Twentieth, which picked up a second-season option with Seacrest less than a month ago and which Tuesday described him as bringing "a high level of talent and class to the industry," could be back in business with him on another project.

An "appropriate project" would be a strong possibility, a Twentieth spokesman said Tuesday.
