In the United States, Showtime had aired all six of Anthony Joshua's world title fights - starting with his title winning effort over Charles Martin to capture the IBF crown in 2016.
On September 22nd, Joshua (21-0, 20 KOs) will make his debut on DAZN - which is the streaming service operated by Perform Group. The service goes live in the United States on September 10.
Joshua will face WBA mandatory challenger Alexander Povetkin at Wembley in London.
Joshua's promoter, Eddie Hearn of Matchroom Sport, cut an eight year content deal with DAZN - and the Joshua card will be the first even of that venture.
At the moment, Showtime has become the top network for televising boxing events in the United States.
Many had expected Joshua to stay loyal to Showtime, who took a big shot on showcasing the Olympic gold medal winner when other networks showed little interest.
But Joshua says the boxing business is not about loyalty.
He feels the decision to align himself with DAZN is the best move for his career.
"Business isn't about loyalty; it's about making the right decisions for your career," Joshua told CBS Sports.
"We are all working together. There is HBO, DAZN, there's Sky; there is all these other broadcasters, so it's not about 'I'm going to stay put because we are loyal.' It's like being in an abusive relationship -- you have to make moves for the better of your life.
"That's what I'm doing right now, making moves for the better of my career. [DAZN] is a good channel to be a part of, and I honestly believe that. But so is Showtime and so is HBO, Sky Sports. They are all unbelievable broadcasters, and one day I may have a chance to box on HBO because I haven't had that chance. There is no love lost. It's not about being loyal; it's about making the right choices in my career because it doesn't last forever."
