The shift to mobile from desktop has been fast and furious, and just a few years ago many investors would have been flabbergasted to hear that a company like Facebook (FB) - Get Report would ditch its desktop advertising platform to put all of its resources behind mobile.

And that's exactly what the social media juggernaut is doing. But when you look at the numbers, the move actually makes sense. In the most recent quarter, 82% of revenues were generated from mobile, up from less than 60% in the first quarter of 2014 and up from 73% in the same period last year.

The amount of mobile monthly active users has also soared, from less than 300 million in the first quarter of 2011 to more than 1.5 billion. The numbers are staggering and only increasing, so Facebook's move actually makes plenty of sense -- not that we've come to expect anything less from CEO Mark Zuckerberg. 

After a troubling start for Facebook's public launch, the stock has been a monster, climbing almost 400% over the past three years. Talk about performance.

Facebook closed at $119.47 Thursday, up 1.3%.

Video games are a dying breed, right? Apparently not according to the recent figures on Sony's (SNE) - Get Report Playstation 4. The gaming console, which was introduced in November of 2013 recently surpassed 40 million units sold.

Even more impressive? 10 million of those units were sold over the previous six months. This far outpaces the estimates for Microsoft's (MSFT) - Get Report Xbox One and Nintendo's WiiU, which respectively came in at a shade under 21 million and 13.1 million units.

The Playstation actually went from 30 million to 40 million units, faster than it went from 20 million to 30 million. Although the price tag for gaming consoles decline over time, it's still somewhat of a surprise to see such good growth for the PS4.

This bodes well for Sony, obviously, and is something for management to hang its hat on. Although there's been a lot of emphasis on virtual reality this year, Playstation doesn't plan on missing out. 

While the game console is selling well, Sony plans to introduce Playstation VR this fall, which is paired with the PS4 (as opposed to a pricey computer) and cost "just" $399 -- a rather affordable figure in the early days of VR.

Shares of Sony closed at $28.05 Thursday, up 0.5%.

Are you a last minute user of HotelTonight, but prefer the travel comforts of Airbnb? Then this should be the perfect fit for you: Overnight.

As a quick refresher for you non-frequent travelers out there, HotelTonight serves as a last-minute hotel-booking app for those who need to find somewhere to stay with just a few days notice. Generally, the prices are reduced because of the last-minute-ness. Airbnb allows travelers to rent rooms or entire homes/apartments/condos from other owners. But usually, they need some kind of heads up.

That's where Overnight comes in, combining the last minute booking ability of HT and the comforts of Airbnb.

Averaging just 45 seconds for an occupancy response, travelers can quickly find out if they have a place to stay that night. According to the company, the rates are rather affordable as well, averaging 23% less than rooms from HotelTonight in Los Angeles.

The selection process is a little different though. Instead of choosing where to stay, you drop a pin in the app around where you'll be staying, and the hosts come to you -- assuming you don't come off as a murderer or something in your Facebook profile (which is used in the verification process). If they approve the guest, then they'll be able to look at photos and details of the places to stay and decide if they want to stay there.

While the app has just 300 requests per night in Los Angeles, it is growing fast, as host space has climbed 150% month-over-month for the past three months, when Overnight first launched.
