Welcome 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 the end of Microsoft’s CEO search, the launch and confusion around Facebook’s Paper app, the Winter Olympics and why it’s so hard for cord cutters to watch online, and Twitter’s disappointing earnings report.

Microsoft names Satya Nadella new CEO, Bill Gates to be more involved

Microsoft’s search is over, and company veteran Satya Nadella is now the CEO. Nadella has also asked Bill Gates to step down as Chairman and become technology advisor, which will allow him to be more involved in defining Microsoft’s product strategy.

Nadella has been with Microsoft for over 20 years and has been involved in many key lines of business. He has worked on the Office product for businesses, helped build the Bing search engine, and led the Windows Azure cloud platform as well as the company’s server and tools business.

The company’s return to an engineer at the helm has been lauded by pundits, but it remains to be seen whether Microsoft can keep up with Google and Amazon in an increasingly cloud- and mobile-based, decreasingly PC-based world.

Facebook launches Paper app, not cool for app named Paper

Yeah, that headline is confusing, but so are users of Paper. Stay with me here.

Facebook launched Facebook Paper, a mobile news reader app that Digital Trends calls “Half Social Network, Half Flipboard, and Fully Awesome.” The app lets you view your news feed in a whole new way and curates stories based on categories you choose. It’s a beautiful and elegant app.

But 53, a company that has built a sketch app also called Paper, is not happy with Facebook’s naming tactics. Users are confused, and that’s likely to continue until something changes. My guess is that nothing will.

Winter Olympics begin, and (some of) you can watch all the events online and on mobile

The 2014 Winter Olympics started yesterday and NBC is making it pretty tough for cord cutters to watch the games online.

While NBC has received praise for showing every event (except for the opening ceremonies) online and on mobile in real time, this feature is only available for cable and satellite subscribers. Non-subscribers will be able to watch up to 30 minutes of coverage the first time they visit either the website or use the mobile app; after that, they’ll only have access to 5 minutes of free coverage each day.

There’s just too much money to be lost by opening this kind of content to everyone, even in a world where online and mobile viewing is growing by leaps and bounds.

Twitter reports earnings, disappoints investors

Twitter’s virgin quarterly earnings report wasn’t one to celebrate. While the company showed strong revenue growth, the company continues to lose money and more importantly, user growth is slowing down.

The company’s stock tumbled nearly 20% primarily because monthly active users only grew by 3.8%, to a total of 241 million. While Facebook’s user growth is also slowing (3.4% last quarter), Twitter has fewer than one quarter of the leading social network’s monthly active users. The Wall Street Journal also posted this image about Twitter’s Timeline views, which isn’t promising either.

CEO Dick Costolo committed to improving the product and growing the user base. Let’s see what the numbers look like during the next earnings report.
