“Aaron Klein Investigative Radio,” the popular Sunday night talk radio show, has been ranked among the 50 most-listened-to talk radio shows via Internet streaming.

The program is hosted by Breitbart’s Jerusalem bureau chief and senior investigative reporter Aaron Klein.

Klein made the “Power 50” list of Talk Stream Live, which was released on Saturday and sampled more than 6.1 million online listeners during 2015 to produce the report.

The website said it tracked “talk radio show metrics gathered on the internet and collected through our server via TalkStreamLive.com’s Website, Gadgets, iPhone app, Android app and “click-to-listen” links on Social Networks.”

Klein’s program, broadcast on New York’s AM 970 The Answer and NewsTalk 990 AM in Philadelphia, came in at No. 37 in the Internet “power” rankings. The position represents a significant audience gain for Klein, who made the list last year at No. 46.

The ranking is particularly noteworthy since Klein’s broadcast airs only once per week for two hours.  His weekend program beat out major national shows that broadcast three hours a day, five days a week.  Larry Kudlow’s nationally-syndicated weekend talk radio program also made the list.

Klein also consistently makes the radio industry’s highly coveted Talkers’ “Heavy Hundred.” With thousands of weekday shows competing, it is rare for a weekend program to make the list, often cited as the most definitive radio ranking.
