Media giant Harris Publication, which produces a host of gun magazines, announced Thursday that it’s closing its doors due to the rapid growth of digital media.

“The magazine publishing industry has been through turmoil in the face of the rapid ascendance of digital media, changing consumer content preferences, magazine wholesaler struggles and consolidation in the supply chain,” the company said in a statement. “We have tried mightily to persevere against these forces, but have been unable to overcome these challenges.”

The New York company was founded in 1977 and grew to become one of the nation’s largest media companies with more than 75 brands, including more than a dozen gun publications.
