Boost was launched in 1985 as a tough coconut and caramel bar coated in chocolate. It was then relaunched in a further two variants: a peanut and caramel version and a biscuit version. The coconut version is no longer available and the peanut version has again been rebranded as Starbar. The biscuit version is now the standard Boost bar. A further version was launched in the UK in 2002 with a green wrapper containing guarana. It was marketed alongside the biscuit Boost and advertised with the slogan "Boost Guarana: One Step Ahead". However, this was eventually discontinued. For a while Boost was advertised on television by comedy duoReeves and Mortimer. This led to the unconventional advertising slogan "It's slightly rippled with a flat under-side." In Ireland, Boost bars are known as Moro bars. A peanut Moro bar is part of the range. In 2007, there was a limited-edition coconut Moro on sale in Ireland. As of 2015, Moro brand is being phased out and replaced with the Boost brand. The Boost bar has been released in New Zealand under the popular Moro brand as Moro Gold. In 2009, the Boost packaging was redesigned and now includes the Cadbury name on the front. The Boost Duo was also launched; two smaller Boost bars in one wrapper. 2013saw Cadbury's elliptical device scrapped on the standard Boost bar, this was however replaced by a new triangular logo device. In late 2010, the Boost Stix bar was introduced in Australia and is a two finger bar much like a Twix bar. In 2013, Boost Max Choc was introduced to Australia. The bar is coated in Cadbury chocolate and made of chewy chocolate caramel surrounding a mixed smooth chocolate and crispy chocolate biscuit centre. The bars are 58g each. Following increased commodity prices and legislation from the Government, the Boost bar in the United Kingdom was shrunk from 60g down to 48.5g in 2013. In 2014, the Boost Duo version also shrank by 10g to 68g. The wrapper was notably updated to reflect the new Reference Intakes and use of Palm and Shea fat in the product. In 2017, the UnitedKingdom multipack version stood at 40g, though it now stands at 34g, as of 2020.
