Welcome to the history of the heavyweight championship of the world.
Yahoo Sport will release a podcast led by legend Steve Bunce for each year of the golden age of boxing; the 1960s.
This podcast covers 1963. The story of the year was the rematch between Sonny Liston and Floyd Patterson, as Patterson attempted to win back the title.

While Liston prepared for the fight, Muhammad Ali – then known as Cassius Clay – goaded the champion into a foul-mouthed outburst and, possibly, a threat with a handgun in a crowded casino.
After a fight between Liston and Patterson that ended in boos from the crowd, Ali and Liston were already selling their future bout to the public.
Before then, Britain’s Henry Cooper would take on Ali at Wembley Stadium. For a brief moment, Ali appeared to be suffering from hubris before his coach stepped in to exploit a tear in his glove to bring about a controversial result.
