Fred Barnes, Eric Burns, Neil Cavuto, John Gibson, E.D. Hill, Colonel David Hunt, Brian Kilmeade, Judge Andrew Napolitano, Bill O’Reilly, Bill Sammon, and Eric Shawn – the list sounds like a network schedule. But these are just some of the Fox News hosts, correspondents, or analysts who have recently published books. People often bandy about terms like “corporate synergy.” The power of the Fox News brand may show where – and how – it’s actually working.

The co-host of “Fox and Friends,” Mr. Kilmeade, said he talked about his book, “The Games Do Count: America’s Best and Brightest on the Power of Sports” (ReganBooks), on his own show when it first came out, and the book was given away as a trivia prize as well. He was also on air on Mr. O’Reilly’s and Mr. Cavuto’s shows to talk about his book. ReganBooks held a party for him at one of the studios at Fox.

As authors, cable TV hosts, analysts, and correspondents have more potential marketing reach than ordinary authors, because they have a built-in “platform” for promoting their books. “They are on TV night after night, and nothing sells books like massive television exposure,” said a book agent from Janklow & Nesbit, Eric Simonoff, who represents Mr. O’Reilly and Colonel Hunt.

“The O’Reilly Factor” sold more than 1 million copies. His book “The No Spin Zone” remained at no. 1 for eight weeks on the Publishers Weekly best-seller list in 2001. Mr. O’Reilly’s Web site helps with sales: In his “store,” one can buy his books as well as sweatshirts, mugs, hats, key chains, and tote bags. And several Web sites of cable hosts invite visitors to join as “members.”

On Sean Hannity’s official Web site, the “Hannity Book Club” features “Strategery” (Regnery), by the Fox News Channel political analyst Bill Sammon, along with other Fox authors including Messrs. Cavuto, North, and Hunt, as well as two books by Newt Gingrich, who is a political contributor to Fox News. Mr. Hannity’s site also has a link to the Conservative Book Club, where Mr. Sammon’s book is a “hot new member” pick.

During the concluding segment of “The Beltway Boys,” Mort Kondracke has more than once praised “Rebel in Chief” (Crown Forum), written by his fellow host, Mr. Barnes. The book “has also been mentioned on ‘Hannity and Colmes’ and ‘Fox and Friends,'” a senior editor at Crown Forum, Jed Donahue, said.

All of this adds up to “a publicity vehicle that is not necessarily available to most authors,” Max Pulsinelli, of Maximum Impact Public Relations LLC, said.This comes at a time when publishers are increasingly “promotion-challenged” and face budget tightening, the chairman of Whitney Radio, Bill O’Shaughnessy, said.

There’s a web of connections among various players at Fox. Fox co-host Mr. Barnes is also a senior editor at the Weekly Standard, which is edited by William Kristol, who is a Fox News political contributor and regular contributor to “Special Report with Brit Hume.” Judith Regan of ReganBooks is a former Fox host of “Judith Regan Tonight” and has published Mr. Hannity’s book “Deliver Us From Evil.” ReganBooks is an imprint of HarperCollins, which, like Fox News and the Weekly Standard, is owned by News Corporation.

“Fox sells itself in a way I’m not sure other news networks even attempt,” OpinionJournal.com editor James Taranto said. Fox News Channel has been rated no. 1 among cable channels for more than four years. In the first quarter of this year, it had the top six cable news shows, and 11 of the top 12.

Should a cable or radio host promote his book on his own show? “Look, all radio talk show hosts talk about their lives,” a senior vice president for news and talk programming at Westwood One, Bart Tessler, said. If a host has written a book, that’s also part of his life, he added. Mr. Tessler’s company distributes Mr. O’Reilly’s radio show, which can be heard on more than 400 stations nationwide.

A senior vice president for programming at Fox, Bill Shine, said Fox hosts are allowed to talk about their books on their shows but should not overdo it. He said there is no formal Fox policy on this. CNN and MSNBC did not return requests for information about whether they have corporate standards and practices on this matter. Mr. Shine said he considers books “an interesting aside” but not what TV personalities are hired for at the network.

Although Messrs. O’Reilly and Hannity are both Fox television hosts, Westwood One distributes Mr. O’Reilly’s radio show and ABC distributes Mr. Hannity’s. Mr. Tessler said the two were unlikely to appear much on each other’s radio shows, since it could upset affiliates – for example, where Mr. Hannity’s show on ABC radio competes in a local market against a show on Westwood One.

But, Mr. Tessler said, they might be welcome during morning drive time shows on their own radio station affiliates.(Mr. O’Reilly has about 400 such affiliates.) A Fox cable author like Mr. O’Reilly might also appear on network television shows such as “Good Morning America” to promote his books to reach viewers who might not tune into Fox, Mr. Simonoff noted. “Bill O’Reilly’s television audience is huge and very loyal to him, and he captures a very significant portion of it each time he publishes a book, but, like other cable figures, is always looking to expand his reach.”

One way a Fox host may reach wider audiences is through newspaper columns. Mr. O’Reilly wrote two articles in the New York Post (which, like Fox News, is owned by News Corporation) in 2002, on crime; two in 2005, one on the pope the other on Howard Dean, and a recent op-ed in the New York Post about religion.

A senior editor at Nelson Current, Joel Miller, said the worlds of ideas and entertainment have become more blurred than in the past. “The Napolitano brand is very visible across the Fox news network,” he said, discussing Judge Napolitano’s book “The Constitution in Exile” (Nelson Current), which features his face on the cover of the book. A number of people follow authors because they are celebrities, Mr. Miller said.

Of course, cable news hosts have skills that can help translate into success as authors. “They have honed their message on air over time and usually have a very clear idea what they want to say in a book,” Mr. Simonoff said.

The publisher of Talkers magazine, Michael Harrison, said news hosts are “good storytellers and they know what topics work and they’re aware of modern attention spans.” And these authors understand how to write for a specific readership, in the same way that they speak to a specific viewership.

“I write the way I talk,” Mr. Kilmeade said. (The founder of Public Affairs, Peter Osnos, was more skeptical. He said just because a person can play the violin doesn’t mean he can play the trombone.)

“They know who their constituency is,” the president of Regnery Publishing, Marji Ross, said. “Cable television is a much more targeted venue, and that’s why cable show hosts who are authors ‘pre-qualify’ as those who know their audience very well.”

Another advantage cable hosts have over many other authors in marketing is being comfortable before a camera. They need “little, if any, media training,” Mr. Pulsinelli said. What might a cable host still need to learn? “That there is a distinct difference in knowing how to interview someone and how to be interviewed,” Mr. Pulsinelli said.

As a guest on a show, an author can help book sales by staying on message, bringing the subject back to the book, and making frequent reference to the book, Craig Shirley, of Shirley and Banister Public Affairs, said. Mr. Shirley makes sure the producer of the show has a digital image of the book’s cover so that he can “chyron” it (that is, superimpose it on screen) during the segment.

An associate publisher at Sentinel, Will Weisser, said Fox was very supportive of John Gibson’s book “The War on Christmas.” Sometimes the relationship is closer: Ms. Ross said Fox and Regnery entered a business relationship whereby Oliver North’s “War Stories” (Regnery) included a DVD of the Fox show with the book. The first two books in the series made the best-seller list.

But one disadvantage to being a cable host author is “their schedule is not their own,” Ms. Ross said. Mr. North was dispatched to Iraq by Fox, adversely impacting the marketing for the third book.

Not all book editors are excited by certain books by cable television news personalities. “These are the people who tend to do books rather than write books,” an editor at large at Doubleday, Adam Bellow, said. “It’s part of their personal merchandising strategy.”

But the literary editor of National Review, Michael Potemra, said he was surprised at how good many of the books were. Then he said he realized “the reason they become famous was that they chose a line of work in which they had to think about public affairs.”

“Books are here to stay,” Mr. Shirley said. “There is a permanent conservative infrastructure through cable television, conservative publications, talk radio, and the Internet, including bloggers.”

The buzz that cable news or talk radio can create for books may inhere in its very structure. It offers a chance for freer banter than its more somber network counterparts. And “network news is – even now – about authority,” Nicholas Lemann wrote in the New Yorker, while “cable news, increasingly, is about itself.”

Mr. Kilmeade said that when he was on book tour, a lot of people were fascinated by how Fox came out of nowhere. “They want to know how we did it.” He said he felt a little like the 1969 Mets, who were “built to win but a lot of people were slow to realize it.”
