Red Sox fans no longer have to be in the vicinity of their couch to watch the team’s games on NESN.

The network announced the launch of its NESNgo app Tuesday, which will provide live in-market streaming of all Red Sox games that it is broadcasting.

Live streaming is available through the network’s home territory — New England, excluding Fairfield Country, Conn.

NESN reached a licensing agreement with Major League Baseball Advanced Media (MLBAM) earlier this year and had soft-launched the app a few months ago.

The streaming offering is available without any additional costs to authenticated subscribers who already have NESN in their channel lineup from participating television providers. Viewers will need to sign in using their existing TV service provider username and password.

Streaming can be accessed via NESNgo.com and the NESNgo app for mobile phones and tablets, which is available in both the iTunes and Google Play App Stores.

Per NESN, over the next few months, some cable distributors are expected to enable NESN live streaming on their own “TV Everywhere” app and/or on their company website.

With NESNgo fans can watch NESN 24 hours a day including Red Sox pre- and post-game coverage, Red Sox games, NESN’s sports news programs, and the network’s entire programming lineup with the exception of Bruins telecasts at this time.

TV service providers that have currently activated authentication for NESN’s live streaming include: Xfinity (Comcast), Cox Communications, MetroCast, PlayStation Vue and RCN, which collectively represent more than half of the cable subscribers in NESN’s home territory.

Other distributors have plans to authenticate NESN streaming in the coming weeks according to the network.
