Media titans back Hirschhorn newsletter

Entrepreneur Jason Hirschhorn has raised $2.25 million in debt financing from a host of media industry titans to expand his free daily media and tech e-mail newsletter into a subscription model.

The newsletter, Media ReDEF (short for “redefined”), aggregates non-breaking, analytical content about all manner of media and technology, and includes tweets, videos and text links to controversial topics.

Hirschhorn, who got rich after he and business partner Blake Krikorian sold video recording device Slingbox to Dish Network in 2007 for $380 million, raised money from investors including Bloomberg Beta, The Chernin Group, Jeffrey Katzenberg, James Murdoch, and sports agent Casey Wasserman — alongside other bold-faced names, such as art collector Jean Pigozzi.

(Murdoch is on the board of News Corp, which owns The Post, and is the son of Rupert Murdoch, News Corp’s executive chairman).

Hirschhorn is a veteran of digital media — having served as co-president of MySpace and Chief Digital Officer at MTV Networks before joining Sling.

Hirschhorn has already hired six people for his Manhattan-based start-up and is building out its Web site and an app — scheduled to bow this summer.

The newsletter has a small but influential daily readership of about 40,000.

“When I was at Viacom, no one wanted to hear what I had to say, so I forwarded articles around and it morphed from links that were generic to a brand that is my personality,” Hirschhorn told The Post. “It’s a mix of media, tech and pop culture.”

The 43-year-old executive said he will add topics, including sports, education, health and design.

The company will also get into the conference business with a series of talks that will have executives from different industry solve knotty business issues.
