Twitter's live streaming app Periscope launched late in the last quarter, and Twitter just shared some stats on its adoption — according to CEO Dick Costolo, 1 million users signed in to Periscope in the first 10 days following its launch. That's only a small percentage of the 300 million active users Twitter announced in its earnings call today, but it points to the quickly growing interest users have in live-streaming videos from wherever they are. Meerkat may have gotten a lot of attention and interest early on — and also raised a lot of money — but the tight integration with Twitter and a more polished product seems to have put the momentum in Periscope's favor.
The question is whether Periscope will continue to grow and prove to be an app users keep coming back to, but it appears making video work is going to be a priority for Twitter. Costolo said on Twitter's earnings call that the company was bullish on native Twitter video in all forms, including Periscope and Vine. He also pointed to last night's riots in Baltimore as a key way for video to enhance Twitter — he called the footage coming out of the city "riveting."
