WWE Network said Monday that it has 667,287 paying subscribers since bowing in February, and predicts it will reach its goal of 1 million users by the end of the year.

The announcement comes following "WrestleMania 30," which aired on Sunday on WWE Network and on pay-per-view.

WWE Network launched as a streaming-only channel, where subscribers pay $9.99 per month -- with a six month commitment -- to receive access to live events and library content.

Although today's numbers are encouraging for the company, they likely capture the network's lowest-hanging fruit -- die-hard wrestling fans who more or less rushed to try the new offering. It remains to be seen how long WWE Network can continue to add subscribers at a rapid clip, and how many continue their subscriptions after their six-month commitment.

There aren't many entertainment-based equivalents to serve as comparisons. Glenn Beck's streaming network TheBlaze, a more talk-centric offering that began operations in 2011 as GBTV, said it had about 300,000 subscribers as of July. GBTV costs $9.95 per month.

WWE Network does not currently include advertising, but company executives said it will begin selling sponsorships and 30-second spots this summer.

WWE is also seeking a new home for "Monday Night Raw" and "Friday Night SmackDown," after the exclusive negotiating period with NBC Universal expired in February.
