Add Periscope as the latest company allowing people to broadcast live from their smartphones.
"Our vision for Periscope was it would feel like a teleportation experience where you can just sort of travel the world through someone else's eyes in real time," co-founder Kayvon Beykpour said.
San Francisco-based Twitter acquired the company last month and launched the app this week.
"I think the biggest plus is being able to see what's happening anywhere in the world," said Ben Parr, author of "Captivology."
And, like the web itself, there is no limit to the reach in real time.
"Something like Periscope will take all these people that you know that are in the far reaches of the Twitterverse and shrink all those distances and bring all those connections closer to you," said Jasmine Bina, a Periscope user.
Thanks to apps like Periscope and Meerkat, anyone can follow and stream their every move.
The numbers for Periscope have been especially high these days because the service is under Twitter, which has tens of millions of people broadcasting every minute.
The app's popularity is exploding.
"Ringo Starr was on Periscope yesterday and Aaron Paul the actor from Breaking Bad takes us into his living room for acoustic guitar concerts," Beykpour said. "The creativity of how users have been playing with Periscope has been nothing short of mind-boggling."
But using the app does come with some risk of seeing indecent exposure or bullying.
"I think the big negative is the combination of the trolling and the lack of control," Parr said. "I think you will see something bad happen at some point."
Periscope said if bullying or indecent exposure were to happen, there are measures in place.
"Periscope is not a place for harassment and abuse. It's also not a place for pornography," Beykpour said. "We have tools in place and teams in place to make sure that policy is being adhered to as much as possible."
Beykpour said they are constantly working to improve the apps' uses and options.
For now, he hopes people enjoy the sights and sounds across the world on your phone.
