While Hollywood has tried to get the story of the rivalry between Apple visionary Steve Jobs and Microsoft trailblazer Bill Gates right, Steve Wozniak had a front-row seat as it went down in real time.

Wozniak was the cofounder and technical genius behind Apple. In that role, he was the man who brought Jobs' visions to life. Over the years, he would get to know both Jobs and Gates very well as Apple and Microsoft weaved in and out of being competitors and partners.

During a press call on Wednesday for National Geographic Channel's "American Genius," Wozniak explained the main difference between Jobs and Gates.

He said Jobs had "a very futuristic forward vision, almost a bit of the science fiction, 'Here’s what life could be,' but Bill Gates had more of an execution ability to build the things that are needed now, to build a company now, make the profits now, in the short-term.

"I think that was the biggest difference between them," he said.

"You really need the vision like Steve Jobs had, but the vision doesn't go anywhere if you try to jump in and build products before they are cost effective for what they do, return on investment is there," he said.

Wozniak added: "It was during the time of the Macintosh that the world market grew 10 times and Apple did not go up with it."

"American Genius: Jobs vs. Gates" premieres Monday, June 1, at 9 p.m. on National Geographic Channel.
