Here Is a List of Celebrities Who Are Already on Meerkat and Periscope

Jimmy Fallon, Madonna, Shaq, Rand Paul and many more

As we've learned throughout social media history, celebrities often drive consumer adoption of new websites and apps. Actor Ashton Kutcher and Twitter are often cited as the ultimate example of a successful marriage, forged in the platform's early days. 

Well, this week, we've had a startup rivalry emerge: South by Southwest darling Meerkat versus Twitter-owned Periscope. Both apps—which are like social-video versions of Apple's FaceTime—are attracting scores of stars.

One would be hard-pressed to dig up two competing services that went mainstream in less than a month like Meerkat and Periscope have.

Check out the famous folks—such as Jimmy Fallon, Al Roker, Questlove Gomez and Arnold Schwarzenegger, who are on both—who are live streaming via smartphone. (The lists below should not be considered complete, as people are downloading each app constantly right now.)
