Over the last few months, there has been growing evidence that online surveillance conducted by the U.S. government is impacting the tech industry. One area in particular? Cloud Storage. Tech companies have started to move some of their facilities overseas under pressure from foreign governments. And some of those governments have considered building their own infrastructure, so that their citizens information won’t be stored in the U.S. Germany’s talking about a so-called Bundes Cloud. But our friend at Harvard University’s Berkman Center for Internet and Society, Jonathan Zittrain, says all this stuff is wrong-headed. 

Will Oremus, tech blogger at Slate joins us to play this week’s Silicon Tally. Plus, the online food delivery service – GrubHub — begins trading on the New York Stock Exchange. The company could raise around $176 million. In fact, the pre-IPO price has moved higher over the past few months, even before it started trading on Wall Street. Why is it so attractive to investors?

Julie Angwin, ProPublica reporter and author of Dragnet Nation: A Quest for Privacy, Security, and Freedom in a World of Relentless Surveillance, talks about why privacy is a luxury. Plus: Molly Wood, tech columnist for the New York Times on Amazon’s new video streaming device, Fire TV. We take a look at what separates this gadget from an already crowded market. And later, Americans spent 70 billion dollars on gift cards last year, but nearly $8 billion worth of those purchased gift cards go unused. The parent company of coin-counting kiosk Coinstar and DVD rental service Redbox launched a new service to turn those old gift cards in your wallet to cash.   

Microsoft is feeling pretty good at the moment — new CEO, its stock is up, and there’s even Office for iPad. Microsoft will now unveil its version of a Siri device. Why has it taken so long?  And what does this signal about how Microsoft is positioning itself? Plus: April Rinne, Chief Strategy Officer, Collaborative Lab, talks about Airbnb’s decision to collect hotel taxes for rentals in San Francisco. After, FTC Chairwoman Edith Ramirez joins Ben for a conversation about data security and consumer protection ahead of a Homeland Security hearing on the topic Wednesday morning.

If you know about the history of the Internet, you know that — while Al Gore might be most famous for supposedly inventing it — it is the Department of Defense that can probably lay claim in earnest. The Advanced Research Projects Agency began building the networks that would become the Internet in the 1960s. And today the current form of that organization, the Defense Advanced Research Projects Agency (DARPA), is launching an office that will focus on biological technology — making synthetic tissues, quickly developing vaccines and connecting the brains of wounded soldiers to new prosthesis.

This week Microsoft’s Build conference kicks off in San Francisco. Build is an event designed to get developers excited about making things for its windows operating system, for mobile devices and PCs. And that’s been a challenge, because as app ecosystems go, Microsoft’s hasn’t been particularly vibrant in comparison to those of Apple and Android. There may be some light poking through the clouds though. Plus: Studies have been done on the effectiveness of treating addiction with smartphones, and the reviews are mixed. But there’s a new program at the University of Wisconsin that aims to support addicts after they leave a residential program. And it seems to be helping people stay sober.

Microsoft has now released versions of its Office software for the iPad. That news came in CEO Satya Nadella’s first press conference as the company head. Analysts say it’s been a long time coming — prevented by the company’s hope that Office could be used to boost sales of tablets based on the Windows operating system. Plus, play along with Marketplace Tech’s Friday numbers game: Silicon Tally.

Microsoft’s Satya Nadella will host his first press conference as CEO of the company. As its new leader, Nadella has his work cut out for him — while Microsoft’s business and cloud computing products have surged, hardware like its Surface tablet have not done so well. The new CEO might be about to announce that Microsoft Office software can now run on more devices. And it’s Spring Break. That means a lot of families are spending more time together than usual. And teens have a lot of extra time on their hands to overuse technology. But parents should remember: Those living in glass houses shouldn’t throw smart phones.

King, the company that makes the wildly addictive mobile game Candy Crush, has its initial public offering today. The company’s been valued at as much as $7.6 billion. But like so many 80s bands you’ve heard and never heard of, King might be a bit of a one hit wonder. Beyond the company’s big game are the lesser knowns worth the dollar bills? Plus, the story behind the eight foot tall robots directing traffic in Kinshasa.
