Black Friday sales push Jeff Bezos' net worth over $100bn

Mr Bezos is the first person to hit that level since Microsoft co-founder Bill Gates in 1999.

It came as sales over the internet overall shot up by almost a fifth (18.4%) on the day - as shoppers snapped up bargains - compared to the same 24-hour period previous year, figures show.

It was gathered that Bezos' fortune went up $2.4 billion to $100.3 billion, as the online retailer's shares jumped more than 2 percent on optimism for Black Friday sales.

Amazon founder Jeff Bezos has become the world's richest person after soaring Black Friday sales and a banner year for his company.

The online retail mogul surpassed Gates as the world's richest man last month, according to the Bloomberg Billionaire Index, a daily ranking of the world's 500 richest people. Gates, 62, who has a net worth of $86.8 billion according to the Bloomberg index, although Bloomberg indicates he would be worth more than $150 billion if he hadn't given $700 million Microsoft Corp. shares and $2.9 billion of cash and other assets to charity.

Forbes, which also tracks real-time net worth, put Bezos at $99.6 billion.

At the start 2017, Bezos was the fourth richest person in the world and surpassed both Inditex founder Amancio Ortega and Berkshire Hathaway's Warren Buffet this year as well. This past June he asked Twitter for ideas on how to be a better philanthropist. Bezos' increase in net worth this year is partly due to an exceptionally profitable year for Amazon, which saw the acquisition of Whole Foods.

He wrote: "I'm thinking I want much of my philanthropic activity to be helping people in the here and now - short term - at the intersection of urgent need and lasting impact".
