While some traditional magazine publishers struggle with their first dip into e-commerce, Mental Floss, the "quirky" magazine that has been "selling its readers products for the past decade," is expanding its T-shirt business, which "already generates seven figures in revenue," writes Jennifer Saba. The pub just launched T-shirt Tuesdays, when weekly new T-shirt designs will be for sale.

Newspapers and magazine execs aren't happy that the U.S. Postal Service is getting closer to shutting down Saturday delivery of first-class mail, but some have been experimenting with contingency plans -- especially weekly pubs like Time and Businessweek, where Saturday delivery has been a tradition, writes Andrew Beaujon. The Week's president says the USPS' move presents the pub with "two not-great options that we have to weigh."

Twitter is "getting into bed with television broadcasters and defining success as driving traffic to their programs," as indicated by its just-announced deal with analytics company Bluefin Media, which "specializes in broadcast media" and how it's being discussed on social networks, writes Matthew Ingram. He sees "a couple of potential pitfalls" with this approach, and says he'd "much rather Twitter focused on filtering and curating the broader universe of discussion around important issues than boosting the viewership numbers of 'The Biggest Loser.'"

The new trend of "binge-viewing" -- watching as many episodes of possible of a TV show, perhaps a whole season, in one seating -- was "in full force" during the first weekend that Netflix's entry into original content, "House of Cards" was available, "according to data from Procera Networks, which found on one broadband network that about one-quarter of those who watched the first episode motored through all 13 episodes," writes Andrew Wallenstein. "Of course, viewing levels only means so much to a streaming service that doesn't carry advertising," he adds. "What percentage of those watchers are new subs is …

In the wake of last week's New York Times staff buyouts, why hasn't there been any "real glimpse inside the newsroom, no sense of what the rank and file are feeling, no temperature-taking"? asks media reporter Doree Shafir. "Until very recently, the Times was the towering institution in American media, the object of endless fascination and obsession," but now "the intrigue behind the walls of the old-school media giants that I was obsessed with back in 2006 and 2007 — the Times, the Wall Street Journal, Condé Nast — seems much less, well, intriguing when the narrative hinges on layoffs, …

Legacy media companies experimenting with a "profitable model" for their ecommerce efforts are finding "it’s a lot harder than it looks," according to "veterans of the space" cited by Emma Bazilian. She examines the difficulties, from lack of "a merchandising strategy as meticulous as [print media's] editorial strategy," according to one source, to "getting consumers to transition from browsing to buying."

NBC is extending its out-of-home reach in Philadelphia, equipping 1,200 taxis with "video screens that stream NBC10 news updates, weather, CNBC business news, and NBCUniversal entertainment to cab hoppers," writes Bob Fernandez. Previously there were 100 cabs so equipped. There are 12,000 cabs streaming NBC content -- more than half in New York City, with others in Boston, Miami, San Francisco, Las Vegas, Chicago, and Dallas.

In its fourth quarter earnings statement, Gannett reports "significantly higher circulation" due to paywalls for its digital newspaper content, which "more than offset a decline in advertising revenues." The company has been rolling  out paywalls for its newspapers (except for USA Today) since last February.

BowTie Inc., which publishes pet and other specialty magazines and books, including Cat Fancy and Dog Fancy, has sold its assets to l-5 Publishing LLC, a new joint venture formed by the CTO of a commercial printer and a co-founder of a publisher marketing company. Financial terms were not disclosed, beyond the quote that it was "an eight-figure commitment." There will be layoffs, though "the new owners plan to retain more than two-thirds of the BowTie workforce," writes Richard Clough.

Teen Vogue, now celebrating 10 years of publication, is doing well, with 2012 fourth quarter ad pages up by 8.3% -- a big leap over its mother publication's upsurge (0.3%) during that time. It's also survived the demise of many other teen pubs, from Cosmo Girl! to YM, and has a circulation that's "hovered at slightly over one million for the last five years," writes Christine Haugney. "Magazine industry experts say that’s notable because its editors are catering to a readership with a narrow age range that outgrows the magazine every few years." One of the secrets to …
