Snap Inc. officially files for IPO

So far, Snapchat has had an easy time keeping information to itself because it was not a publicly traded company.

Apple's 'polarizing' new products are paying off

During 2016, it seemed like lots of Apple fans were unhappy. The year brought few updates to the Mac, a barely redesigned iPhone with no headphone jack, AirPod headphones that shipped two months late and a new Apple Watch that was a modest improvement to a product still seen as nonessential. However, Apple just reported a massively successful quarter. According to CEO Tim Cook, both iPhone and Apple Watch sales hit records for both unit sales and revenue. In the case of the iPhone, that reversed three consecutive quarters of declining sales. Further still, Mac sales also generated record revenue, despite the fact that the new MacBook Pro was limited in supply and the rest of Apple's computer lineup hasn't been updated in a long time.

Classic racing series 'GTR' will return in 2018

It's taken more than a decade, but GTR 2 is finally getting a sequel. SimBin says that GTR 3 is being built on the Unreal 4 engine and is just months into development. However, we're already getting a few ideas about what will feature in the game. Chris Speed, the CEO of SimBin's parent company Sector3, confirmed that the game would feature a day-night cycle, dynamic weather and vehicle damage. Further still, dynamic water movement will mean rain can pool organically, which will lead to aquaplaning and other handling quirks. 2018 is a ways off, and the game still needs to find a publisher and some form of licensing: the FIA GT Championship that the game series was previously built from no longer exists.

Outstanding but pricey.
