CP+B Miami launched its first TV ad for letgo, a mobile app that lets users post, buy and sell items. The app lets users communicate with potential buyers for free. The debut ad, "Cliff," shows how much emotional meaning material items have to owners. We see a man dangling off a cliff and holding on to an overturned tractor trailer with one hand. The man's other hand is holding his beloved bowling ball, which he clearly loves more than life itself. His friend, out of harm's way, posts the bowling ball for sale on …

I can only imagine the number of earplugs used during the making of this ad for Sony's MHC-V7D speaker. The video illustrates what sounds look like, via a series of Cymatics experiments. If the MHC-V7D can make water and sand dance, imagine what it will bring to a house party, aside from tinnitus? It's interesting to watch, from a scientific perspective. First, a petri dish filled with vodka is placed on a sub-woofer, where the music makes the liquid move in mysterious ways. Next, a thin metal sheet covered with sand is attached above …

Building on Nike Women's global "Better For It" platform, Nike Russia launched a campaign that celebrates the "Real Girls of Moscow," a group of the country's top female athletes who are changing the way that women and sports are portrayed. In the first ad, we see a woman hold an extreme yoga pose for what seems like forever. It's beyond impressive. See it here. Next, there's a a trail runner who prefers her mud mask to come from nature, rather than a spa. Watch it here. The inner thoughts of a boxer …

Ebates, a site that pays consumers for shopping online, launched a TV spot highlighting the sheer number of checks it sends to members. One man fills the position of check writer, and it's akin to a competitive sport, since he needs to sign a crazy amount of checks. Sure, he could have someone help, but he prefers to go it alone. Would a follow-up ad focus on the check writer's carpal tunnel? See the ad here, created by EVB and directed by Jared Hess.

Random iPhone App of the week: Social platform Sayer launched an iPhone app where users can crowdsource opinions and predictions on thought-provoking questions. Users can also pose their own questions, called "Sooths," to their friends and the Sayer community. Sooths come in two forms: predictions and polls. A Sooth can cover an array of subjects and interests, and can include a link to external content. The Sooth is then published for the community to weigh in on. Users can challenge friends to answer Sooths via SMS, Facebook, Twitter and other social media channels.

Grab a tissue. Ads for cereal and gum will make you cry. Let's launch!

Mattel launched a campaign for Barbie that positions the brand as a force for girl power.  In "Imagine The Possibilities," a series of young girls are working high-level jobs, much to the surprise of the adults around them. Girls hold the roles of soccer coach, college professor, veterinarian, museum tour guide and sales executive, while hidden cameras watch the reactions of unsuspecting adults. My favorite is the young girl gabbing on the phone in an airport and watching the nearby adults try to contain their laughter. I'm also partial to the soccer coach who …

Company Chairman Gert Boyle is back -- and so is her no-nonsense attitude -- in a massive print, OOH and TV campaign for Columbia Sportswear. Boyle makes cameo appearances in each of the three TV spots where Columbia gear is tested in extreme conditions by company employees. Employee orientation at Columbia involves stranding newbies on a ski lift in frigid temps, with Boyle delivering dinner in a cherry picker. See it here. I'm more impressed that a printer, buried in snow, still works in "Snow Shovel." No snow day for the employee who …

This seems to be the week when advertising is tugging at heartstrings. First, we had Cheerios and its touching spot about a man who moves in with his daughter and her family, and now we have a beautiful love story told through gum wrappers. This isn't the first tear-jerking ad from Extra Gum; the brand launched a multiple-tissue ad two years ago about the special bond between a father and daughter. "The Story of Sarah & Juan" is set to Haley Reinhart's cover of "I Can’t Help Falling in Love," and tells …

Cheerios has a knack for tugging at viewer's heartstrings -- and the brand's latest ad, "Grandpa," is no different. An adult daughter helps her aging father, unable to live alone, pack and move in with her. The car ride home is quiet, and it's clear that the man is apprehensive of the move. That all changes when the man is greeted at home by his adorable granddaughter. She doesn't know what flavor Cheerios her grandpa likes, so she has a variety of flavors on the kitchen table for him to choose from. Watch …
