Björn Borg encourages people to spread love instead of insults on social media. The tone on Twitter is very negative lately, especially when it comes to politics. The brand says: our rivals make us better. That’s why Björn Borg presents the world’s first Twitter Punching Bag, in Stockholm. This is an interactive punching bag with a printed alphabet, and it’s connected to Twitter. When someone punches a letter, this becomes a letter in a tweet.
