How likely is world peace? Probably about as likely as bottles doing synchronised swimming ...

With the world firmly focused on events in Iraq for the past few months, it now seems apt to focus instead on a Brazilian ad promoting peace. Even more so because, in contrast to the graphic images of war sent back from Baghdad, W/Brazil's spot for national broadcaster Rede Globo has no visuals at all apart from a gradually intensifying ripple on a white screen.

Instead, a calm and measured voice tells us about peace as a product, suggesting that whilst humans may have bought it, it has yet to be delivered. Considering the ad was broadcast during the network's most-watched programme - 25 million people tune in for Fantastico in Brazil on Sunday afternoons - the decision to eliminate visuals was a particularly brave one.

But the writing is strong enough to work on its own, especially when the person delivering it has the authority of experience to 'sell' the idea of peace - Washington Olivetto, the agency's president and creator of the ad was kidnapped and held for 53 days last year.

Since then, his status as a national treasure has soared, and although some are cynical about the motives behind his involvement in Rede Globo's national peace initiative, what better way is there to get the message across to the public than by using someone with some real memories of the horror of violence?

And now for something completely different. Whoever it was at New York agency Deutsch who suggested strapping miniature horns on a hutchful of furry rodents and letting them loose in a parody of the running of the bulls in Pamplona, had clearly been drinking Snapple. In a market dominated by brands like Coca-Cola and Pepsi and their multi-million dollar spends, it makes sense for a brand like Snapple to seek stand-out through wit.

This it does brilliantly with a series of ads involving men-crazy lady bottles ogling a stripper, a pastiche of the wedding scene in The Graduate and a swimming pool full of synchronised acrobatic bottles.

The brand's long-standing strategy to personalise itself shows no signs of wearing thin, and the home-grown feel of the ads links in well with other strands of the campaign, including a web-based yard-sale using Snapple bottletops as currency.

After 20 years of Nestle's famous slogan "Do you love anyone enough to give them your last Rolo?" the confectionery king has finally ditched the catchphrase that made those tasty bites a household name. Bound to cause a stir in the British press, Nestle's new ballsy campaign - armed with its hip new strapline "Discover the power of the last Rolo" - apparently reflects the declining romantic mood of the modern-day Briton.

This is backed by research, commissioned by Nestle, that discovered women are much more demanding than their contemporaries 20 years ago. This, of course, sparked a series of press articles analysing the modern-day romance, which ranged from the love/hate relationship with Valentines day to tastes in chocolate.
