The office that once belonged to Steven P. Jobs still does, according to Apple's CEO Time Cook, as it has remained just as the company's co-founder left it when he died.

According to Billboard, Cook sat down with Charlie Rose to discuss several topics, Jobs' legacy among them. Cook also discussed the iPhone 6, Apple's acquisition of Beats Music and television.

The first part of Rose's interview with Cook aired Friday, Sept. 12, the same day Apple allowed customers to start preordering the iPhone 6 and 6 Plus. Apple set a new iPhone sales record with more than four million units preordered in the first 24 hours of availability.

Part two of the interview will air Monday, Sept. 15.

"He's in my heart and he's deep in Apple's DNA," Cook told Rose of Jobs' legacy with Apple. "His spirit will always be the foundation of the company. I literally think about him everyday... His office is still left as it was on the fourth floor, his name is still on the door."

Predictably enough, Cook did not discuss Apple's future plans, but he may have tipped off what the next innovation might be. According to CNET, Apple has been rumored to be developing a television set.

He told Rose he thinks the television experience is currently "stuck in the '70s."

"[It] almost feels like you're rewinding the clock and you've entered a time capsule, and you're going backward," Cook said, but would not discuss the supposed Apple TV set or any other future innovation.

The Apple CEO told Rose he was sold on Beats Music's subscription for having a unique listener experience. He called Beats co-founders Dr. Dre and Jimmy Iovine "creative geniuses."

But Cook also said he was not expecting to get the chance to run Apple, but realized Jobs had put a lot of though into naming his successor. He said he was surprised when Jobs named him the next CEO because the two were different people, something Cook has embraced.

However, there was at least one private aspect of the Apple CEO who was publicly a demanding, borderline-tyrannical perfectionist.

"He was a great teacher," Cook told Rose. "This is something that's never written about him."

Jobs was obviously passionate, but he especially cared about mentorship and would really make sure people understood what he was trying to say.

"It's teaching and making sure people are learning, and him taking such an interest that he's going out of his way to do this," Cook said. "And I think it's missed - it's a huge, huge part of what he did that's missed in most of the things that I've read."
