The Cannes Film Grand Prix-winning Old Spice campaign has evolved over the last 24 hours to dominate discussion in social media, in what is sure to become the ‘case study du jour’ for the foreseeable future.

“The Man Your Man Could Smell Like” spot from Wieden + Kennedy Portland was launched in February during the Super Bowl. It featured Isaiah Mustafa, a former NFL athlete, being totally awesome and became an almost immediate hit online. It has since racked up almost 13 million views on YouTube, with a couple new iterations launched in recent weeks.

Yesterday, however, the marketing campaign took a different turn and really got ‘social media right’. It’s been updated and sees Isaiah Mustafa respond directly to YouTube comments, Tweets, Yahoo! Answers and blog posts about him in 117 publicly available, timely and personalised video messages.

To ensure maximum coverage Old Spice replied to some of the most popular personalities on Twitter, such as @Biz (Twitter co-founder), @ryanseacrest (TV personality), @kevinrose (Digg founder), @Alyssa_Milano (actor), and @guykawasaki (social media thought leader). Blogger Perez Hilton’ s video response has already clocked up over 115k views. They’ve also hit up media outlets like GQ, Huffington Post, Gizmodo and The Ellen Show. Starbucks have even managed to get in on the action.

So what are the results? It’s still early to tell, but a few things are apparent.

The activity, according to Campaign, appears to be targeted at the ‘Twitter generation’ and it seems to be doing the trick. There has been a noticeable increase in followers to the @oldspice account, as well as a surge in conversation volume about the brand over the past 24 hours.

Searches for “old spice” or oldspice for the last week up until 10.45am today turned up the following:

That’s pretty spectacular, and the volumes were enough for Old Spice to trend on Twitter. What’s interesting though, is that Old Spice started yesterday as a Twitter Promoted Trend, but quickly ‘earned’ the status. TechCrunch explains:

[Old Spice] also just redefined the model for Promoted Trends. Old Spice is a promoted Trend, which takes you to the Old Spice Twitter account highlighting these videos as individual responses addressing each Twitter user who gets their own Old Spice commercial. The irony is that if Old Spice hadn’t paid to be a promoted Trend, it probably would have made it as a Trending Topic organically.

This morning Old Spice is still trending, organically.

There has been a similar increase in discussion on blogs as well. Again, a simple search for “old spice” or oldspice for the last week up until 11.45am today turned up the following:

But a key question is: can this goodwill and online buzz translate into sales?

Though the original adverts have been a massive hits, and clocked up millions of views on YouTube, sales of Old Spice haven’t necessarily seen the same upward trend. Just yesterday AdWeek reported that sales of the Old Spice body wash have actually dropped 7 percent over the last year.

So this surge of social media activity certainly comes at an interesting time, and it will be worth keeping an eye on, especially as brands like Dominos Pizza publicly pin their good fortunes on social media activity.

Ultimately, this level of social media engagement which was born from a television advert is really remarkable. Old Spice has done a great job in updating the campaign so that it really ‘works’ online. Most importantly though, the video responses are consistently funny in their own right, making it hard not to love this campaign.

So on that note, we’ll leave you with Isaiah Mustafa’s responses to The Huffington Post, Guy Kawasaki and Perez Hilton – some of the finest examples:

Update: ReadWriteWeb has the lowdown on how the Old Spice videos are being made:

A team of creatives, tech geeks, marketers and writers gathered in an undisclosed location in Portland, Oregon yesterday and produced 87 short comedic YouTube videos about Old Spice. In real time. They leveraged Twitter, Facebook, Reddit and blogs. They dared to touch the wild beasts of 4chan and they lived to tell the tale. Everybody loved it; those videos and 74 more made so far today have now been viewed more than 4 million times and counting. Here’s how it’s going down…

Fast Company also have an interview with our old friend Iain Tait who’s been working on the project:

One of the unique things taking place in the studio is we have a team of social media people, we have the Old Spice community manager, we have a social media strategist, a couple of technical people, and a producer. And we’ve built an application that scans the Internet looking for mentions and allows us to look at the influence of those people and also what they’ve said. They’re working in collaboration with the creative team that are there to pick out the messages that: 1. Have creative opportunity to produce amazing content; or 2. Have the ability to then embed themselves in an interesting or virally relevant community.

Iain also gives more background on the project on his own blog.

And now it seems, the end has arrived, with this closing message from Isaiah:

Update 2: We’ve conducted some in-depth analysis into the results of the campaign – Old Spice videos viewed 11 million times.

Update 3: Wieden+Kennedy have released a nice video case study of the campaign.

Zappos lives up to its reputation for customer service
Over the past few years, online retailer Zappos has been highlighted alongside the likes of Ford, Dell or Comcast fairly regularly as a ‘go to’ case study for their use of social media for customer support. And it’s easy to see why with this example.

A pricing bug on a Zappos sister site called 6pm.com gave customers the ability to purchase any product online for no more than $49.99. The mistake was eventually caught 6 hours after it went live, but not before customers had taken advantage of the pricing bug to the tune of approximately $1.6m.

Balancing the backlash that might ensue online against the cost of eating the loss, Director of Brand Marketing Aaron Magness explained on the Zappos Blog that they would honour all purchases.

As Econsultancy’s Patricio Robles put it: “Zappos… clearly understands that its reputation is worth far more than $1.6m and that sometimes eating a loss is the smart thing to do. Interestingly, one might even suggest that Zappos will only boost its reputation and customer loyalty with this move.”

Independent blocks anonymous comments
The Independent dealt a blow to trolls everywhere by only allowing people to post comments if they sign in using their Facebook, Twitter, Yahoo, Open ID or Disqus accounts. Editor Martin King explained the move with the following:

Websites have been encouraging cowardice. They allow users to hide behind virtual anonymity to make hasty, ill-researched and often intemperate comments regardless of any consideration for personal hurt or corporate damage.

Well said. While this might not be able to stop individuals posting under a pseudonym using, say, a Disqus account, it is nonetheless a step in the right direction to try and deter those who seek only to defame or abuse in comments sections across the web.

BBC iPlayer adds Twitter and Facebook to socialise TV
The BBC’s video on demand service, iPlayer, is launching iPlayer Beta at the end of June, allowing users to link their Twitter, Facebook and Windows Live Messenger accounts to their ‘BBC ID.’

Users will more easily be able to share what they’re watching over social networks, while viewers using Windows Messenger can sync viewing with friends and chat about the show in realtime.

Buy lettuce, get virtual currency
Social gaming company Zynga and Green Giant have teamed up to offer purchasers of Green Giant vegetable products free virtual currency that can be used in Farmville.

At first glance, the promotion seems like a very good fit. Zynga will be able to easily track redemptions to determine if the promotion is a success, while Green Giant can (hopefully) get more people eating their ‘5 a day.’ More importantly though, “the promotion highlights just how prominent virtual currency and games like Farmville have become in the mainstream.”

BP beaten in social media stakes by fake tweets
BP has had something of a mess on its hands lately in social media in the form of a tongue-and-cheek account:  @BPGlobalPR. The account has swelled to over 97,000 followers, eclipsing BP’s official @BP_America account by some 88,000, and claimed to be the oil giant’s official voice throughout the ecological crisis in the Gulf, while delivering a healthy dose of satire.

The anonymous Tweeter has since penned an editorial in the Guardian, been unmasked by Wired magazine and even given a book deal. There is also a T-Shirt range with proceeds going to benefit the Gulf Restoration Network. Long may it continue.

Dr Pepper rolls out Facebook status takeover for teens
Coca-Cola has launched a Facebook app for Dr. Pepper which gives consumers the chance to win £1,000 if they allow Dr Pepper to take control of their status update.

The app ties into their ‘What’s the Worst that Could Happen?’ creative, and chooses updates at random with varying degrees of embarrassment such as ‘what’s wrong with peeing in the shower?’ or ‘never heard of it described as “cute” before.’

Domino’s UK Rewards Foursquare Mayors, Yahoo acquires ‘Asian Foursquare’
Domino’s UK is starting a nationwide Foursquare promotion that rewards mayors with free pizza once a week, a deal similar to the one Starbucks announced not too long ago. Additionally, every Foursquare user will receive a free side dish when spending over £10.

In other location-based news, Yahoo has acquired Koprol which has been described affectionately by TechCrunch as the ‘Asian Foursquare.’

Google Moderator on YouTube enables real-time feedback from your audience
YouTube has integrated the use of Google Moderator into every single YouTube channel. Google Moderator is a social platform that allows users to solicit ideas, ask questions, and have their community vote for the best comments in real-time. Crucially, it also allows users channel owners the ability to remove any content that their audience has flagged as inappropriate.

Twitter passes 15 billion tweet mark
After reaching 10 billion tweets at the beginning of March, Twitter has now announced that it has delivered its 15 billionth tweet:

It took Twitter almost a year to hit five billion, but only four months to hit 10 billion. By adding another five billion tweets in three months it is now growing at more than one billion tweets a month, which means it should hit 20 billion before the summer is out.

Assuming we even get a summer in London this year…

Dr. Michael Wesch, Assistant Professor of Cultural Anthropology at Kansas State University, a pioneer in digital ethnography and the man who brought us Web 2.0 … The Machine is Us/ing Us and Information R/evolution presents an anthropological introduction to YouTube to the Library of Congress:

I know you’ve been shown this video before, but have you actually watched the whole fifty-five minutes and thirty-three seconds of it? I did last night, and all I can say is that you’ll be wiser for it.
