Until recently, Starbucks didn’t do much -- or really, any -- TV advertising. That’s changed, but Starbucks doesn’t see its YouTube channel merely as a dumping ground for new ads. Instead, there’s a lot of extra content, including some exclusive stuff with musicians like Jakob Dylan, Broken Bells, James Mercer of the Shins.

In the video above, Mercer plays Broken Bells’ track "The High Road" to a focus group of British kids. “I didn’t like the synthesizer bits in the chorus,” says one of them, “and it’s a bit dark.”

In addition, there are commercials for the brand, information about where Starbucks gets its coffee, and interviews with Starbucks employees.

Orabrush is a real product, but you still might want to check out the brand’s YouTube channel even if you’re not in the market for a new oral care solution.

Since 2009, Orabrush has been cranking out one zany video after another that resemble Funny Or Die bits more than standard commercials. For instance, Orabrush the Movie, shown here, presents the company’s creation story as a gritty independent flick. Best of all perhaps is Orabrush’s iPad 2 parody, which will change the way you look at Apple’s ads forever.

Choice quotes: “We have a great product that’s revolutionized the world. So what? Are we going to sit around in front of a white screen in turtlenecks bragging about it all day?” and “Give me a choice between the cure to cancer and the cure to bad breath and I’d take the Orabrush.”

Some brands have all the luck. GoPro has an advantage over many other brands in that its product line -- wearable HD cameras for sports -- happens to be the perfect one to be shilling in the age of YouTube.

Naturally, the brand’s YouTube page features video after video of POV shots from athletes recording their feats on one of the cameras. Some of them are even in 3D. Spend some time on the site and you’ll never look at an avalanche cliff jump the same way again.

Call it propaganda, if you will, but there’s no denying that this is really good propaganda.

Watch enough of the content Walmart's channel -- which ranges from TV commercials, to stories from Walmart employees, to testimonials from “Walmart Moms” who save money at the store -- and you’ll be ready to conclude that this is the best company in the world.

Like Starbucks, Walmart’s YouTube site is a great example of a brand that’s providing a range of content that never strays far from its marketed image. There’s nothing on either site that feels like it doesn’t belong or doesn’t promote the brand in some way.

Procter & Gamble’s stomach care brand is on this list because it’s one of the few (and maybe the only) brands to use its channel to host a game.

On Cinco de Mayo, the brand introduced Pinata Smash, which let you make your own pinata-smashing video with variables for the pinata, the filling and the smasher. The program didn’t set the world on fire -- each video got in the five-digit range for views -- but it did suggest some new possibilities for YouTube as a social media marketing vehicle.
