In "Google Stock Sinks as Mobile Struggles Continue" by James O'Toole, explains how Google shares sank 3% in after-hours trading Wednesday after the company posted first-quarter earnings and sales that missed expectations. Of particular concern was a 9% drop in payments from marketers per ad on Google sites.

The challenge for Google is convincing marketers to pay as much for mobile ads as they do for desktop ads, a task that's become increasingly pressing as Web usage shifts to smartphones.

In "How Phones Work in Flight" talks about the lack of phone calls, texts or social media postings from missing Malaysia Airlines Flight 370 which raised a number of questions about how cell phones work on airplanes. Despite the urgings of flight crews to turn off all phones or put them in airplane mode, cell phones can continue to work after a plane takes off, but only while in range of a cellular tower.

Cell phones communicate through cell towers, which are located on the ground but can stretch hundreds of feet into the air. As an airplane rises, it gets further from these towers and eventually moves out of contact range. For efficiency, many towers are designed to direct their signal where its most useful: on the ground, not into the sky above.

"Over the Top is coming" is surprising Verizon's executives because the future of television is so bright. First, consider the situation today.

Internet streaming through services like Netflix and Hulu are still the exceptions to the rule. The future looks like a mash-up of these two modes of viewing; a bundle of channels that are streamed via the Internet to any and every screen.
