Apple

While Apple unveils a futuristic new smart watch, Amazon slashes prices on its smartphone for shoppers. Both companies are searching for the innovation sweet spot in mobile.

On the eve of the next trial in the continuing patent war between Apple and Samsung, one of the iPhone's original designers is speaking out publicly for the first time.

In Silicon Valley, zero profit and even zero revenue don't make a company a loser. Tech companies like Snapchat and Twitter, which have not yet turned any profit, can be worth billions of dollars based on future potential alone.
