In today's WWE 2018 earnings release, the company announced that paid subscriptions to their WWE Network streaming service have risen to "approximately" 1.59 million paid subscribers.
WWE noted in the release they are developing the "next iteration" of the Network, which likely means the long-planned tiered version.
1.59M seems like a pretty solid number, anyone remember where they were number-wise way back when the network launched, and figures they were hoping for in order to consider it a success? Seems like a lifetime ago in a way.
If I recall correctly, the number they mentioned was 2 million.
