If you've been using Periscope for a while you'll know that your 'scopes' disappear within 24 hours. There was a service called Katch, that would save your scopes for you, but it recently closed down.
Periscope is now testing out permanent save options. Right now it's in public beta and all you have to do is include #save in your caption.
Of course you can still go back and delete it afterwards if you decide you don't actually want it to be available forever.
Soon there will be an option within the app to set the time limit without having to include the save hashtag.
Personally I'm all for the new option, because you'll be able to link to great scopes permanently, there will be no more ugly 'this Periscope has expired' messages on Twitter, and you'll be able to embed great videos into other sites.
What do you think, would you like to be able to save some Periscopes permanently?
