The reason is obvious: These three companies dominate the smartphone industry with a shocking totality.
Google dominates mobile search revenue in part because of its Android platform and in part because of its iOS apps. Google made about $5.2 billion in mobile ad revenue last year worldwide and grabbed an incredible 93.3% share of the U.S. mobile search ad market.
The rest of the industry is fed up with watching Apple, Samsung and Google run away with all the money. Now they're fighting back.
The industry is competing again and they're doing it right -- with innovation, imagination, design and sound strategy.

Apple didn't have a booth, yet had a presence at MWC not unlike Lord Voldemort's in the Harry Potter series -- the scary, powerful entity that must not be named.
A general mob scene at the HTC booth involved long lines forming behind the dozens of tethered demo units of the recently announced HTC One phone. Many people were snapping pictures of the HTC One with their iPhones.
