CLEVELAND, Ohio -- iHeartMedia, the largest owner of radio stations in the U.S., announced plans Tuesday for a "new organizational structure" and "technology transformation" that will result in layoffs across its more than 850 member stations.

The company isn’t releasing specifics about the number of jobs being eliminated-- iHeart scrubbed all employee bio pages from its stations’ websites, making it difficult to track. The number, however, is reportedly in the hundreds and perhaps exceeds 1,000 employees.

iHeart owns more than a dozen stations in the Cleveland-Akron-Canton market. Though smaller markets seem to be taking the brunt of it, 96.5 KISS FM, Cleveland’s Top 40 station, was hit hard. An industry source told cleveland.com most of the station’s on-air staff were let go.

Majic 105.7 also suffered layoffs, according to All Access. Afternoon drive host Don “Action” Jackson, disc jockey (and WGAR personality) Jim Hart, and weekend host (and Sunny 101.7/99.7 Canton afternoon drive host) Scott Davidson lost their jobs.

In a Facebook post Tuesday, Jackson admitted he was caught off guard by the news after 18 years on the afternoon drive.

“While getting the news today was a bit devastating, I am proud of the work I did there in afternoons for the last 18 years, and nationally for iHeart for about the last 10,” he wrote. “Not sure where the road will take me next, but thankfully, I’ll have some nice memories of the people I worked with there, in some cases like family. I will miss you very much.”

In its announcement, iHeartMedia said it will reorganize the company into four divisions and leverage advancements made in technology and artificial intelligence to consolidate all aspects of its business from programming and podcasts to marketing and sales.

“We are modernizing our company to take advantage of the significant investments we have made in new technology and aligning our operating structure to match the technology-powered businesses we are now in,” an iHeartMedia spokesperson said in a statement. "During a transition like this it’s reasonable to expect that there will be some shifts in jobs – some by location and some by function – but the number is relatively small given our overall employee base of 12,500.

“That said, we recognize that the loss of any job is significant; we take that responsibility seriously and have been thoughtful in the process.”

Chairman and CEO Bob Pittman said the changes were about "setting us apart from traditional media companies; improving our services to our consumers and advertising partners; and enhancing the work environment for our employees.”

In an internal memo obtained by All Access, Pittman along with iHeart President and COO Rich Bressler acknowledged the employees that were laid off.

“Please know we were thoughtful in this process and have provided enhanced severance benefits as well as outplacement assistance for any impacted employees, and we want to thank them for the valuable contributions they have made,” they wrote.
