The congratulatory message from his sponsor was tweeted out immediately after Murray’s victory and has now received more than 12,000 retweets, including one from Murray himself.
Murray claimed the Sports Personality of the Year award last night after a public vote and his victory comes after he has had to battle against accusations throughout his professional career that he lacks charisma.
The 26-year-old Scot’s victory at last night’s awards is confirmation that perceptions of him have turned a corner following events including him breaking down into tears after his runner-up position at the 2012 Wimbledon final, and a documentary about his life.
Murray’s growing reputation has seen him hire a branding agency to create a Roger Federer-style personalised logo that will appear in a new Adidas range and across accessories such as his Head racquets.
Even last night, Murray drew criticism for not attending the Sports Personality of the Year ceremony and instead accepted his prize at his training camp in Miami via a video link.
Murray told the BBC: "I'd like to thank all the public who voted, for giving me so much support over the last couple of years. It's made a huge difference."
Murray, who this year became the first male Briton to win a singles Wimbledon title in 77 years, beat British and Irish Lions rugby union player Leigh Halfpenny and jockey AP McCoy to the prize. Halfpenny and McCoy came second and third respectively.
