Time is the only constant and over a period of time, everything around us changes. Even people go through a lot of changes in their lives, from their physical appearances to their status, their wealth quotient and many other things. Here is a look at some of the most popular world CEOs, and how they changed over a period of time

Jeff Bezos

Before Bezos’ name got attached to Amazon, he was the senior VP with D.E. Shaw, a hedge fund and then in 1993, he decided to sell books on the Internet. Amazon sold books to people in all 50 states and 45 countries in the first month itself and on May 15, 1997, it went public. Since then it has only seen an upward growth.

Today, the year 2019, Jeff Bezos is the wealthiest person on the face of this earth with a net worth of $150 billion. The 78,893,033 shares that he holds in Amazon account for his 16.3% stake in the company.

Mark Zuckerberg

A 20-year-old Mark Zuckerberg formed Facebook when he was studying at Harvard University in 2004. He dropped out of school to give his social network full time and raised $12.7 million in its first round of funding.

Mark Zuckerberg founded “The Facebook” when he was 20 years old in 2004 while studying at Harvard University.

Facebook’s initial public offering in 2012 was the biggest-ever technology IPO at the time.

Steve Jobs and Steve Wozniak started Apple Computer Company in 1976 in Jobs’ garage. Jobs was just 21.

Jobs was the brains while Wozniak was the engineer. In 1984, Apple released its first personal computer, the Macintosh.

In 1985 Jobs left after a clash with CEO John Sculley and 12 years later Apple bought over Job’s startup NeXT Computer. After that Job started the new era of Apple products and introduced the iPhone and iPad.

In 2003, he was diagnosed with a unique form of pancreatic cancer.

Before going for medical leave in August 2011, Jobs handed over the reins of the company to Tim Cook and died at the age of 56. Jobs was looked upon one of the best CEOs in the world and there was a lot of uncertainty over how things would turn for Apple after him.

In 2015, Cook pioneered and released the Apple Watch, the company’s first entirely new product in the post-Jobs era.

Today, Apple is worth $1 trillion under Cook, 58. It was worth about $330 billion at the time that Jobs passed. Its market cap is close to $675 billion and is one of the most valuable companies in the world.
