Starbar was Cabury's first real attempt to establish a competitor for Mars' Marathon / Snickers bar. Initially popular in the mid-1970s, the Starbar largely exists due to a small but loyal fanbase, as the product has not been advertised or promoted for years. In the mid-70s Starbar was called Nunch, and its TV advertisement featured a dark-haired woman walking alongside a white horse which was pulling a barge down a canal. Nunch was rebranded Nudge and in the 1980s it briefly became "peanut Boost," only to return to Starbar as popularity of the Boost bar waned.
