So, it isn't bad enough that Tiger Woods ruined his marriage and soiled his squeaky-clean reputation. Apparently he cost his corporate sponsors $12 billion in stock value as well. According to a study conducted by UC Davis economics professors Victor Stango and Christopher Knittel, Tiger lost his sponsors a "collective $5 to $12 billion." This loss outpaces "several decades' worth of Tiger Woods' personal endorsement income."

The study examined the stock market returns during the 13 trading days after Tiger's car crash, a period concluding a week after Tiger's announcement of an indefinite leave of absent. The two economics professors then compared the returns for Tiger's sponsors during this 13-day period to those of the total stock market and each of the companies' closest competitor. Returns for the four years prior to the car accident were also taken into account in order to establish the stocks' historic performance.

Five of the largest companies in the print business are testing the digital waters together. Rather than yield their content to alien formats, Time Inc. (TWX), News Corp. (NWS), Conde Nast, Hearst and Meredith Corp. have announced plans to develop a digital content format of their own. This new product would compete with the newly released Nook from Barnes & Noble (BKS), as well as one from Sony (SNE) and the industry-leading Kindle from Amazon (AMZN). The new e-reader content will come in color and in a format that would work across several devices.

The five media companies are equal partners in this joint venture, which will allow publishers to set their own prices for their content -- an obvious response to what they see as unfavorable revenue share deals offered by Amazon earlier this year. Rupert Murdoch has been particularly vocal on this issue, particularly about the fact that News Corp. only receives a little more than a third of the $14.99 a month it costs to subscribe to the Wall Street Journal on a Kindle. He says of the device that it's "a fantastic invention for reading books. It is not much of an experience for newspapers."

The broader economy is showing signs that we can at least interpret as positive, but this doesn't extend to the media industry, it seems. Condé Nast's ad page results are out for its 2009 issues, now that the last issue of the year has been sold for each of them ... and the situation is grim.

Condé Nast lost 8,359 ad pages this year, according to a report released on Wednesday. Ad pages have plunged 30% this year. Cost cutting has been used to offset the revenue declines, with more than 450 positions removed this year and several magazines shuttered, including Gourmet and Modern Bride.

Sotheby's (NYSE: BID) had a great night this week, tripling the performance of competitor Christie's (OTC: CRUPF). But, it didn't come soon enough to help the company's third quarter results.

The auction house suffered from the art market slump that was exacerbated by the global financial crisis, posting a net loss of $57.8 million (89 cents a share). This is worse than the $47 million loss (73 cents a share) it delivered a year earlier. Three analysts that Bloomberg surveyed expected a loss of 29 cents a share. Revenue was off 41% to $44.9 million for the quarter.

Vibe, the urban music magazine, is clawing its way back to life. New owners and editors are trying to make the magazine a success reality again, and they are making the web a priority ... which shouldn't be news but is for an ailing print industry.

The new editor-in-chief, Jermaine Hall, told AdAge that "Vibe.com is really the hub," and that everything needs to point back to the online presence. The print publication will be just one part of the Vibe Lifestyle Network, a move we're also seeing with the likes of Rolling Stone, where the website is being brought back into the fold (and may actually get some resources).

The mayhem in the media industry continues. The Wall Street Journal, a News Corp (NASDAQ: NWS) property, is closing its Boston bureau and sending nine employees into the wind. The newswire and MarketWatch operations are going to stay open in Boston, however, with no headcount impact.

The Journal doesn't have any plans to close other offices, according to a memo by managing editor Robert Thomson: "there are no plans, nascent or otherwise, to close any other U.S. or international bureau." The WSJ will still support an "investigative function" in Boston, but the New York-based Money and Investing team will cover Boston's mutual fund industry, which boasts such heavy hitters as Fidelity.

At the same time, magazine company Time Inc., owned by Time Warner (NYSE: TWX) is looking to cut $100 million in expenses, and layoffs will undoubtedly figure into the equation. The company that owns Time, Fortune, People and Sports Illustrated – and falls under the same umbrella as AOL, which owns BloggingStocks – is feeling the squeeze of a media recession that's even worse than the regular recession we've all been battling for what feels like decades.

Printers of the world unite! Feeling the squeeze from the likes of Amazon (NASDAQ: AMZN) and Apple (NASDAQ: AAPL), a group of magazine publishers is forming an industrywide joint venture ... for protection.

Led by Time Inc., a division of Time Warner (NYSE: TWX), participating companies would create a digital storefront for their content. In this way, they could peddle their goods without the hefty carve-outs that come with Amazon and Apple deals.

Conde Nast is ditching Domino, the "style magazine that focuses on life at home." The magazine was launched in April of 2005, and CEO Charles H. Townsend said that the decision to abandon the projects was driven "entirely" by the economy.

The magazine's editor told The New York Times that "We tried to create a marriage between the beautiful image magazines and the useful service magazines. Editorially, we did what we set out to do, and in this economy, sadly, that's not enough."

The magazine was burning cash as its ad revenue declined with the housing industry.

In a time when print magazines such as Life are folding (again) one could argue launching a new magazine is either bold or foolish. Since Condé Nast's new slick Portfolio is focused on business and marketed to executives, one would hope the business decision behind its creation is inspired.

The magazine takes a different tact from Business Week and others that depend on timeliness. Portfolio promises more in-depth, big-picture stories, similar to the editorial content of other CN flagship publications such as GQ, Wired, The New Yorker and Architectural Digest.

Portfolio fills a niche missing in Advance Publication's Condé Nast stable, and will allow it to further leverage advertising sales over a broader demographic. It has launched with an expectation that circulation will hit 350,000 this year, and it plans to market the magazine through American City Business Journals, another branch of the privately-held Advance Publications family.

CN expects the readership to skew 2-1 male, with a median family income over $140,000, household assets in excess of $1.5 million, and investments over $1 million.

I don't expect to receive any subscription offers.
