Buying Latest Apps Helps Web Giants Stay Young
Twitch.tv and Snapchat may have launched only three years ago, but they're already shaping the internet giants YouTube and Facebook - in different ways.
Twitch is an online video platform that lets its users stream videogaming sessions live to anyone who wants to watch.
And they do: Twitch has 45 million users, and the average user watches the site for 90 minutes each day.
The company says that games broadcasting "is only just getting started".
YouTube wants to tap into that growing audience and is set to pay $1bn (£590m) in cash to acquire the platform, according to Variety.
It's a good fit for YouTube, although some will wonder about the valuation.
Another valuation that raised eyebrows last year was $3bn (£1.8bn) - that's how much Facebook offered to buy Snapchat.
Even more surprising, the makers of the ephemeral messaging app turned the offer down.
Facebook didn't like that. So now it's going head-to-head with the start-up.
The FT reports that the social network is working on a video messaging app called Slingshot.
Users will be able to send short video messages with just a couple of taps of a phone's screen.
The Slingshot app would not be incorporated into any of Facebook's existing mobile products.
Instead it would be another standalone app - alongside Messenger, Paper, Instagram and Whatsapp. Facebook is fast becoming a mobile app conglomerate.
So what do the two stories have in common?
Facebook and YouTube are the decade-old incumbents - and it's hard to see anyone completely dislodging them for some time.
But the internet giants are constantly looking for new audiences. For YouTube, this is gamers. For Facebook, it's teenagers - with whom Snapchat is very popular. It's also a demographic Facebook has been struggling to engage.
Hoovering up smaller apps - or copying them - is becoming the default way for the grand old companies of the internet to stay young.
You're only as old as the last app you bought.
