In June, WWE signed licensing deals with Comcast-owned USA Network and Fox-owned Fox Sports starting from Oct. 1, 2019, for its programs "Raw" and "SmackDown." USA Network will distribute "Raw" on Mondays, while Fox will screen "SmackDown" on Fridays as part of the five-year arrangements.
The deals will increase the average annual value of WWE's U.S. distribution to 3.6 times that of the prior deal with NBCUniversal, which is also owned by Comcast.
That means "Raw" and "SmackDown" could go from $270 million in revenue to almost $600 million in three years, Barrios told CNBC.
The sports entertainment company also reported second-quarter earnings on Thursday that missed expectations, but it scored a major revenue beat.
Revenues increased 31 percent to $281.6 million, an all-time high. Network subscribers were up 10 percent, while digital views jumped 60 percent.
The WWE has made a big investment in digital and specifically in social media. It has 900 million social followers and is the No. 2 channel on YouTube, Barrios said.
"We've been at it for 10 years," he said.
While some people early on weren't sure about digital and social, "We decided to err on going all in," he added. "At the end of the day we set the strategy, put the resources in place, worked like crazy, and that's where we are today."
