Zuck Chan baby

Hope everyone had a great Thanksgiving! Welcome back to “The Week in Tech,” where we recap some of the most interesting technology and mobile stories from the past week.

This week we cover Mark Zuckerberg’s charitable vow, Yahoo’s potential sale, Cyber Monday revenues, and Apple’s possible plans for smaller iPhones.

Mark Zuckerberg has a kid, then vows to give away 99% of his wealth

Having a child really changes the way you think.

After his wife gave birth to a baby daughter, Facebook CEO Mark Zuckerberg announced in a letter to his newborn that he will give away 99% of his Facebook shares – currently valued at $45 billion – over his lifetime to better the world.

Zuckerberg and wife Priscilla Chan created the Chan Zuckerberg Initiative as the vehicle to “advance human potential and promote equality for all children in the next generation.”

While much of the money will go to charitable causes, it won’t all go to charity. The Chan Zuckerberg Initiative was formed as an LLC, allowing it to fund non-profit organizations as well as make private investments to improve personalized learning, help cure diseases, and connect people.

Yahoo may sell its internet business

Yahoo’s Board of Directors is considering a sale of the company’s core internet business as the turnaround led by CEO Marissa Mayer struggles.

While Yahoo’s properties attract hundreds of millions visitors per month, the company is a mere afterthought in advertiser budgets when compared to rivals Google and Facebook. Yahoo’s revenue is stagnant, with only 7% year-over-year growth in Q3 of 2015. And even though the company has been active in acquiring companies, it has not been able to successfully monetize these properties, nor create new products that resonate with users.

It’s unclear how much a sale would fetch. At the moment, Yahoo is valued at around $31 billion dollars. But its 15% stake in Chinese e-commerce giant Alibaba is worth about $32 billion; thus, Yahoo’s internet business has a negative valuation. That’s funny, not in a good way.

Companies interested in Yahoo’s assets include various private equity firms, Verizon, IAC, and News Corp.

Cyber Monday sales top $3 billion

For the first time ever, sales on Cyber Monday surpassed $3 billion. According to Adobe’s Digital Index, total online sales on November 30 hit $3.07 billion, a 16% bump from last year.

Sales on mobile devices also broke a record, with $799 million of revenue being generated from a smartphone or tablet. Mobile accounted for nearly half of all internet traffic that day.

Amazon absolutely dominated Cyber Monday, accounting for over 36% of all online sales. Best Buy was a distant second (5.5%), followed by Walmart at 3.8%.

Many retailers continued to offer deals throughout the week to keep the holiday shopping season momentum going.

Apple might release 4-inch iPhone

Apple is believed to be working on a new 4-inch iPhone to be released early in 2016.

The overall trend in smartphones has been bigger, bigger, bigger. Android phones led the charge with “phablets” with screens of 5″ and larger, and the iPhone 6 recently joined the party.

But it seems like Apple recognizes that some of its users yearn for the smaller screen like that of the iPhone 5. And they’re going to include top-of-the-line features like the fast A9 processor, near-field communications to enable Apple Pay, metal casing, and more.

While this may not be a big seller, it’ll satisfy those Apple fans who want to return to days of yore when you could do everything on your phone with one hand.
