REPORTER: It's a year since the wedding of the decade and London toy store Hamleys is celebrating. It's taken delivery of a set of William & Kate dolls. They're made by Mattel - the world's biggest toy maker - and have already sold out in America and on some online websites. Head buyer at Hamleys, Laura Olver, says they're expecting a lot of interest.
LAURA OLVER, HEAD BUYER, HAMLEYS: "Straight after the engagement another manufacturer bought out a Catherine doll in the blue engagement dress which took us by surprise. We sold about 30 times more than we originally forecast we would sell of that doll. And that was no question it was Hamleys' customers who are both tourists and obviously toy shop customers and that combination of the doll and the tourist element meant that we saw fantastic sales of that doll so we're really excited about the potential of this one."
REPORTER: British retailer Tesco was quick to copy Kate's designer engagement dress. Other high street shops favoured by the Duchess of Cambridge have also seen sales soar. And retail analyst Isabel Cavell says she sees no sign of her popularity waning.
ISABEL CAVELL, RETAIL ANALYST: "We're seeing the likes of Reiss perform very well over the year, we're seeing LK Bennet and we're seeing new fashion designers really spring up which she semi endorses like Issa, which are now big names in fashion, so she really does have a major impact. She looks good in what she wears and shoppers want to buy in to that."
REPORTER: At £99 the dolls don't come cheap. But Mattel says they're more of a collector's item than a toy.
RACHEL, TOURIST FROM PERTH: "They're just beautiful, they're a young couple and I think they represent like a modern marriage today and I just love the both of them, they're gorgeous."
BRITISH SHOPPER 1: "It should have been out last year it wouldn't been great but now it's Jubilee and Olympics, it's not them two any more is it."
BRITISH SHOPPER 2: "They're ghastly an absolute travesty no."
REPORTER: So not everyone likes the dolls but one year after their wedding the royal couple are still hugely popular around the globe. And that can only be good news for Britain and the brands they favour. Hayley Platt, Reuters.
Google has replaced its logo with a time-lapse animation of blooming flowers to mark Earth Day, a worldwide series of events held annually to raise ecological awareness.
The latest in the search engine's so-called doodles sees purple, red and yellow flowers sprout from a series of shrubs laid out to spell Google.
Earth Day was first held on 1970 after Gaylord Nelson, a US senator, conceived it as a tool to promote an environmental agenda after witnessing a huge oil spill off the coast of California a year earlier.
Organisers claim the 1970 event rallied millions across the country as it tapped in to the rise of hippie culture and anti-Vietnam war protest movements. "Groups that had been fighting against oil spills, polluting factories and power plants, raw sewage, toxic dumps, pesticides, freeways, the loss of wilderness, and the extinction of wildlife suddenly realised they shared common values," the official Earth Day websitesays.
Major Earth Day events have been held in subsequent years, always on 22 April – the same date as the original event. In 1990 the event went global for the first time with activities involving an estimated 200 million people in 141 countries. The day's 30th anniversary in 2000 was used to promote a global call for cleaner energy while 2010 saw the launch an initiative to plant 1m trees.
This year's Earth Day is centred around a scheme called "one billion acts of green", which encourages individuals to make simple environmentally conscious pledges, such as switching off lightbulbs or reducing car journeys. Organisers say the day is now observed in 192 countries.
