According to The TV Addict, the accounts are named after shows currently on the network's development slate, sparking rumours that the pilots have been picked up.
Summer Glau's The Cape, David E. Kelley's Kindreds and Jerry Bruckheimer's Chase all have pages named after them. They are joined by The Rockford Files, The Strip and Matthew Broderick's Beach Lane.
All of the Twitter accounts begin with "NBC" and are followed by the name or part of the name of the show.
The network reportedly told Variety that NBC has registered Twitter accounts for all the possible programmes, but pages for Friends With Benefits, The Adam Carolla Show, Nathan Vs. Nurture, Our Show, Perfect Couples, The Pink House and This Little Piggy have not yet been found.
NBC has already picked up Love Bites, Outsourced and The Event.
