Levi's backed into some body-image issues in its latest "fit" campaign. It used to be that when a pair of new jeans didn't fit, a young woman thought there was something wrong with her. Now, when new jeans don't fit, she thinks there is something wrong with the jeans. Levi Strauss, one of the world's largest makers of women's jeans, is trying to adapt to that new reality with its Curve ID products and marketing.

For many years, people ate plain old carrots, and they liked them. But carrots weren't very exciting, so clever farmers gave birth to the baby carrot in the 1980s. Convenient, tasty and chock-full of beta carotene, baby carrots were an instant hit with consumers looking for a quick, convenient way to eat veggies. "For 10 or 15 years, the [baby carrot] industry had the tiger by the tail. There was more demand than there was capacity," says Bryan Reese, chief marketing and innovation officer at Bolthouse Farms. But eventually growth slowed.

Biggie Smalls vs. Dumbo Digerati

Every digital DUMBO dude (or dudette) on the go comes equipped with a full complement of iDevices. When networking with other techsters at DigitalDUMBO, the iPhone's the only way to keep in touch and shoot "hipstamatic" photos, then instantly uploaded to the microblogging tool of the moment.

Updating a logo is like plastic surgery. Sometimes it makes something old look young again. Other times, not so much. Gap learned this the hard way in October. Ivy Ross, creative director of marketing, said Gap was moving to "a clean look that represents modern America and is aimed at people who enjoy style and technology." As part of that effort, the company quietly changed the familiar blue-box logo on its web site to plain black type on white with a small blue box in the corner. It mimicked the layout changes already used in the brand's advertising.

The new member of the Jane Austen Society of North America (JASNA) looked sheepish. "Um, I know you ladies don't approve, but I'm thinking of buying a Nook," she said. Some looked puzzled, and a quick tutorial on ebooks ensued. Then Nili Olay, JASNA's New York Metro Region cochair, showed she had her heart in both the 19th and 21st centuries. "Why shouldn't we approve?" she asked. "We want everybody to read as much as they can, any way they can."

Aaron Shapiro wants to take over the world -- a tall order, sure, but slightly more realistic now that he's been named CEO of Interpublic-backed Huge (he was previously responsible for strategic leadership). Bolstered by top-notch work for Pepsi, Target and JetBlue, the Brooklyn-based digital agency has exploded from 10 to 300 employees since 2005 earning its name.

Growing up with the name Rich Will Wanket, this fairly green Minneapolis real estate agent has heard all kinds of jokes related to, well, self-pleasure. Keeping the old adage, "If you can't beat 'em, join 'em," (almost literally) in mind, Wanket did just that. Not in a Pee Wee Herman fashion, but as a befitting newspaper display ad in The Onion. It took two months to manifest, though, and the print ad went viral when someone scanned and posted it to a blog.

This summer, Kim Jong Il and the government of North Korea launched a Twitter feed, officially marking the dawn of a media era characterized by satire and surrealism. The North Korean account, uriminzok, ("Our Nation,") has more than 10,000 followers. You can also watch North Korean propaganda films on its YouTube channel, and follow its official page on Facebook.

Groupon is the stuff startup dreams are made of. The company's group-buying site offering daily deals has proven wildly popular with consumers and won the admiration of retail experts for the elegant simplicity of its business model. Forbes called two-year-old Groupon the "fastest growing company ever," and its success has spawned a series of me-too competitors. Along with the accolades and imitators have come investment dollars - $173 million to date, with the most recent round giving the company a rumored valuation of more than $1 billion and a series G round ready to push that figure higher.
