Just days after Google, Facebook and Apple purged videos and podcasts from the right-wing conspiracy site Infowars from their sites, the Infowars app has become one of the hottest in the country. On Wednesday, Infowars was the No. 1 overall "trending" app on the Google Play store. Among news apps, Infowars was No. 3 on Apple and No. 5 on Google, above all mainstream news organizations. The Infowars app, which includes news articles and the shows of the conspiracy theorist Alex Jones, had likely been downloaded a few hundred to a few thousand times a day on average after its introduction last month, said Randy Nelson ... at Sensor Tower, which tracks app data. Now, it is likely getting 30,000 to 40,000 downloads a day, Mr. Nelson estimated. "This is such a niche app with niche content, that for it to make that sort of jump means it has become very interesting to a much broader audience," said Jonathan Kay, a co-founder of Apptopia, an app analytics firm. "Essentially, it's gone from being niche to being mainstream." Mr. Jones has achieved infamy and financial success for spreading lies. Many of his most outlandish claims are made during his show, which runs live for four hours each weekday and is streamed and rebroadcast across the internet. YouTube, Facebook, Spotify and Apple's podcasts service were all important distribution points for the show.
