An unfortunate winner: the tech companies hoarding more than $2 trillion in offshore tax havens. Those companies benefit from the U.S. education system, intellectual property protection and culture of innovation — and they should pay accordingly.

A loser: fake reviews. Amazon is taking legal action against more than 1,000 anonymous individuals who sell five-star reviews for $5. However, L2 research finds that most reviews are positive anyway.

A continued winner: Uber. But as the “unbelievable app” redefines industries from taxis to food, many are struggling to reconcile themselves to the service economy that the company has created.

A big winner: GoPro for redefining content marketing. The brand leverages user-generated content to dramatic effect: L2’s Digital IQ Index: Consumer Electronics finds that GoPro’s videos have more than 960 million views on YouTube, nearly five times more than those of its closest competitor.
