David Beckham's ad for H&M has risen to be the most-shared ad this week, while viral sensation Sweet Brown makes the most of her internet fame to promote Shortline Dental in the US.

The Guy Richie-directed spot for H&M rises from third place last week to take the most-shared accolade for its second week in the chart, more than 117,000 shares up week on week.

Meanwhile, Sweet Brown, an American woman who became a viral sensation after she was interviewed by a local news team having witnessed a fire, has put her internet fame to use, starring in an ad for Shortline Dental in the US.

With just over 4.1 million views on YouTube, the ad is dwarfed by the 22.2 million views to the remix video that first made her a star.

A Valentine's Day-themed ad from the chocolate brand M&M's, "love ballad" by BDDO, entered the chart in sixth place this week with 44,873 shares.

Last week's most-shared ad, a Super Bowl spot for Budweiser, has fallen into ninth place, a performance echoed, but not matched, by other Super Bowl offerings that dominated last week's most-shared list.

However, an ad from the popular US washing power brand Tide, which was made for the Super Bowl, "miracle stain" by Saatchi & Saatchi, USA, entered the chart for the first time with 38,209 shares this week.
