This feud began back in 2008 when Cuban accused Branson of plagiarism after he published an article that was strikingly similar to one Cuban had published on his blog. The two have been engaged in a back-and-forth ever since, with Branson even going so far as to start a "mark cuban is a billionaire" Google search to try and discredit his rival.
While the two men have been able to set aside their differences for the sake of business (they are both investors on the television show Shark Tank), the water feud still simmers below the surface. In fact, just last year Branson took a shot at Cuban during an interview, saying "I don't get into bed with people like Mark Cuban."
It's unclear what the future holds for this feud, but one thing is for sure: these two billionaires are not going to let it go any time soon.
Richard Branson and Mark Cuban have been engaged in a public feud for years. It all started when Cuban accused Branson of overcharging for water bottles. Branson responded by calling Cuban a "snake oil salesman." The feud has only intensified since then, with the two men exchanging insults both in public and on social media.
Cuban has accused Branson of being a "con artist" and a "liar," while Branson has called Cuban a "cheapskate" and a "scumbag." The feud has even led to physical altercations, with the two men getting into a fistfight on one occasion.
It's unclear how this feud will end, but one thing is for sure: it's entertainment for everyone involved.
The feud between Sir Richard Branson and Mark Cuban started back in 2004 when Cuban accused Branson of being a copycat. The feud escalated when Branson challenged Cuban to a water-drinking contest, which Cuban won. This only made Branson more determined to take down Cuban, and the two have been engaged in a friendly rivalry ever since.
