To mark the third anniversary of Apple co-founder Steve Jobs' death, CEO Tim Cook sent a letter to his employees asking them to reflect on how the inventor changed people's lifestyles through his technological innovations, First Post reported.

Cook sent the letter on Saturday, Oct. 4, which is a day before the death anniversary of Jobs.

"Sunday will mark the third anniversary of Steve's passing," Cook wrote. "I'm sure that many of you will be thinking of him on that day, as I know I will. I hope you'll take a moment to appreciate the many ways Steve made our world better."

"Children learn in new ways thanks to the products he dreamed up," he continued. "The most creative people on earth use them to compose symphonies and pop songs, and write everything from novels to poetry to text messages.

"Steve's life's work produced the canvas on which artists now create masterpieces," the CEO added.

Cook then emphasized that even though Apple's famous leader has passed away, it doesn't mean he is completely gone from the company.

Although a lot of the company's current projects were developed after his passing, Cook noted that the ideas behind them came from his influence, according to Apple Insider.

"Steve's vision extended far beyond the years he was alive, and the values on which he built Apple will always be with us," Cook said. "Many of the ideas and projects we're working on today got started after he died, but his influence on them - and all of us - is unmistakable."

"Enjoy your weekend, and thanks for helping carry Steve's legacy into the future," he added.

Jobs passed away at his home in Palo Alto, California on Oct. 5, 2011. He died due to complications related to pancreatic cancer which resulted to respiratory arrest. He served as Apple's CEO for about 14 years, Time reported.
