Premier Networks issued a list of nearly 100 companies that have requested their ads not run during programs that may contain "offensive or controversial" content, ABC News reported.
Premier said the barter ads suspension will continue through March 23.
They would not say whether the ad pull was in response to a Limbaugh backlash.
More than three-dozen companies pulled ads from Limbaugh's three-hour show after the conservative host used off-color language to describe a Georgetown University law school student who testified before Congress.
Some of the companies, such as Geico and JC Penny, issued statements saying their ads were not specifically purchased for Limbaugh's time slot and were mistakenly run there.
Presumably those were barter ads, ABC said.
