“I am captivated by the story of the rise — and now the fall — of mass media, having devoted my life and career to the institution,” Jeff Jarvis says.

Today the veteran editor, blogger and professor is releasing his next book, “Hot Type: The Magnificent Machine That Gave Birth to Mass Media and Drove Mark Twain Mad.” That machine is the Linotype, “a quirky but brilliant typesetting machine.” I loved imagining a city with dozens of daily newspapers — something the Linotype made possible — and asked Jarvis a bit about it:

Before the mechanization of media was complete – with steam-powered presses, cheap paper made from wood pulp, the telegraph, and the Linotype – the average circulation of a daily newspaper in the U.S. was only 4,000, limited by the power of human muscle to set type and pull the press. The Linotype was critical to bringing scale to publishing.

At the same time, this new industry of mass media had to invent business models to support it. The capitalist villain of my tale, New York Tribune publisher Whitelaw Reid, swore in 1879 that newspapers would never grow past eight pages, as readers would not tolerate more content or advertising. It was a magazine publisher, Frank Munsey, who tried selling his egotistically titled periodical, Munsey’s, for a dime and a loss, betting he would make it up on advertising. Thus was born the business model for publishing at scale: the attention economy that has supported mass media since and now infects the internet.

Following mechanization, publications were thicker with more content and advertising and much larger circulations. But with profitability came consolidation as media moguls and corporations became more powerful. Still, in 1900, New York City boasted 46 daily newspapers. By the 1970s — faced with competition from broadcasting and new technologies — only three were left.

Print newspapers and magazines might die, though they can live on digitally. Note that e-books have not superseded print books. Print is all around us. It will not die. It has new company.

Yes, I do think we are entering what media scholars Walter Ong and Marshall McLuhan referred to as a second orality — in essence, a return to the shape of society before Gutenberg, based more on conversation than content. That is the thesis behind The Gutenberg Parenthesis. We see this revived orality not only in radio and TV but also now in podcasts, on YouTube and TikTok.

I see this as a democratization of media. One need no longer be a writer or own a printing press and typesetting machine to find and speak with a public. Only problem is: After five centuries of print culture, society is out of practice with conversation.

CNN commentator Scott Jennings has been at the forefront of attacking Sen. Jon Ossoff over his comment about Trump aide Natalie Harp, including on CNN’s “NewsNight.” New reporting in Politico Playbook this morning suggests it’s part of a public audition to replace Karoline Leavitt.

Would Jennings really want to give up his CNN and Salem Radio salaries for the unforgiving press secretary job? Well, he met with Susie Wiles about the possibility. And NOTUS reports that Trump “is considering a man to prevent comparisons with” Leavitt.

Asked whether he wants the job, Jennings told Playbook: “I don’t have anything to say about that.”

Trump is scheduled to tape an interview today with Michael Cohen, MS NOW’s Jake Traylor and Vaughn Hillyard scooped.

It’s the latest strange turn in the relationship between the two men. The NYT summed it up this way last month: “Michael Cohen helped convict Trump. Now, he’s making nice again.”

Cohen says parts of the interview will air tonight on WABC, where he hosts a Sunday evening show, with more to come on that show this weekend…

One day after WaPo’s Liam Scott reported that Stars and Stripes’ longtime publisher Max Lederer planned to retire at the end of September, Jennifer Jacobs scooped for CBS that Pentagon officials “have discussed firing” Lederer “before his scheduled retirement.”

A punitive measure, in other words, and maybe a way to send a broader message. In Lederer’s resignation email to staff, he said it “has become clear that my philosophy of leadership, and my understanding of the value and mission of Stars and Stripes, differ in fundamental ways from the direction the leadership of the Department of Defense has for the organization.” The military publication’s editorial independence is clearly at risk.

The NYT’s Elisabeth Bumiller is out with a revealing story about Jennifer Hegseth and “her hands-on role in her husband’s Pentagon.”

Jennifer and Pete Hegseth met at Fox News, where she worked for 18 years. “She is now her husband’s most influential adviser and de facto producer, shaping the job like no Pentagon spouse has before,” Bumiller writes.

Among her contributions: Encouraging battles with the media. “Once Mr. Hegseth was in office, Mrs. Hegseth was eager to revoke the credentials of Pentagon reporters who she felt had written negative stories about her husband,” Bumiller reports, citing sources. Here’s a gift link to the full story…
