Influential mortgage and real estate mogul Dan Gilbert's Bedrock LLC has launched its own magazine to publish stories about Detroit.

TBD, which began publishing online in November and in print last month, describes itself as "a digital and print publication profiling the people, stories and ideas that define Detroit today."

The quarterly print edition sells for $15 and annual subscriptions are $60, and stories are published regularly online, said Whitney Eichinger, director of communications for Bedrock.

"Its brand and editorial content is intentionally independent from Bedrock," she said.

The first print edition was 114 pages and didn't have any advertising, according to Eichinger. It is paid for out of the Bedrock budget.

"We are exploring options for future editions. We have not committed to an advertising model," she said, adding that circulation numbers are not being disclosed.

Bill Stevens with Troy-based Tepel Brothers Printing Inc., which printed TBD, said 5,000 copies of the first issue were produced.

Nick Perold, vice president of marketing, came up with the idea, Eichinger said. Gilbert signed off on the magazine's creation, she said.

Among the recent stories published: A profile of Wallace Detroit Guitars, which is run by Detroit RiverFront Conservancy President and CEO Mark Wallace; a look at a Museum of Contemporary Art and Design exhibition on architecture; and a piece on Antietam restaurant in the Eastern Market district.

TBD has a roster of freelance writers who have written for Crain's Detroit Business, The Detroit News, the Detroit Free Press, Hour Detroit and BLAC magazines, USA Today and the Washington Post, according to their biographies on the TBD website. Story ideas are generated internally by Perold and other Gilbert employees across his dozens of companies, as well as the writers, Eichinger said.

Gilbert has a large influence in the city, purchasing a vast swath of real estate in and around downtown in the last five-plus years and employing thousands of people through his Quicken Loans Inc. and Rock Ventures LLC, companies of which he is founder and chairman.

This isn't Gilbert's first foray into the publishing world. In 2014, a private equity firm he co-founded, Rockbridge Growth Equity LLC, purchased The Robb Report, which reports on luxury lifestyles through magazines, websites, smartphone apps, events and a private club. In December, Penske Media Corp. and Rockbridge announced the formation of a joint venture partnership in The Robb Report, which has an office in Detroit.

TBD and The Robb Report do not share any resources, Eichinger said.
