On Wednesday night's episode of The Late Show with host Stephen Colbert, the chief executive officer of Apple Inc. - Tim Cook, talked about why he finally decided to go public with his sexuality.

The American comedian and television host Stephen Colbert, made a witty remark, "Was that an upgrade, or just a distinctive attribute that hadn't been activated before?"

Joking aside, Stephen Colbert wondered whether it was because the Apple chief executive, who was raised in the conservative South Alabama as a "resonant outsider" felt some sense of responsibility towards those who are being excluded from society because of their sexuality.

Tim Cook, who joined Apple in 1998, said in a statement, "In all the quality of being honest, every day I come to work, I have right in front of my desk, an image of Robert Kennedy and Dr [Martin Luther] King," Tim Cook added, "And every day I sort of ask myself - it was the quote of Doctor King that got me - life's most persistent and urgent question is 'what are you doing for others?'

Tim Cook said that it became clear to him that kids were getting bullied at school are being differentiated from and even being refused acceptance by their own parents. With that he feels he has to do something.

Being someone who values his privacy thought against it, saying maybe he's valuing it far above how he should value lending a hand to other people.

Tim Cook also said that, "Over the years, I've been open with many people about my sexual orientation," Cook added, "Many of the colleagues at Apple know I'm gay, and it doesn't seem to make a difference in how they deal with me in a certain way. Of course, I've had the good fortune to work at a firm that has a fondness in creativity and innovation, and knows it can only develop in a healthy way when you embrace people's differences. Not everyone has the luck."
