This library has a lot of story, i've found this info about network music:
Network Production Music is created by Tom Dinoto, owner of the US commercial jingle company "Tuesday Productions" in San Diego, California. Craig Everett Palmer is the principal composer of many of the successful early cuts, which feature string and French horns on top of a modern drum beat, with Timpani and brass accents.
One Craig Palmer composition -- entitled "Energy" -- practically defined the genre of 1980s production music. Early "Network" cues and themes often were used on TV network sports shows and syndicated US TV shows such as "Lifestyles of the Rich and Famous", and behind national commercials. Network becomes a successful US-owned production music library for this style of music.

In addition of this, craig palmer has made a lot of pieces for network music.
in the 90's network offers other catalogs, classical music cds, and production elements, and a special library only with the broadcast versions of the main cuts (:60, :30, :20, :15 Seconds) called shor trax, but currently all this, are no longer available, only the main library
