Louise Marsland (@Louise_Marsland)’s pick of new product, packaging and design launches this week: January is the time of sales and special offers and even fast food isn’t exempt as KFC cooks up; Native VML shows how branded content works for Jameson; the tinsel has hardly been put away when the shops are slathered in red for Valentine’s Day and “sincere” messages on chocolates; Pepsi takes to the streets; and it turns out the Sodastream deal wasn’t that sweet for Scarlett Johansson.
