Time Warner, the network's majority owner, commissioned IBM (for hardware and infrastructure) and Enterprise Systems Group (later known as Encoda and then Harris Corporation; contracted for software systems at the national and local level) to develop a national data server network that would digitally transmit local and national advertisements, promos, station identifications and customized logo bugs for each individual affiliate to headends operating the local WB 100+ affiliate in their home market. The network would be relayed to a "station in a box" (SIB), a wireless PC-based system that was programmed to download (through a data feed distributed via satellite), store and insert advertising appropriate to the individual affiliate's home market in pre-determined time periods set through a playlist over the satellite-delivered national feed as well as to transfer the programming feeds, via a disseminated address header based on the affiliate's designated call letters. The SIB units – which cost $9,000 per unit – were sold to each prospective affiliate operator with costs fully shouldered by The WB; the SIBs held 90 minutes of programming material at a time, in addition to transmitting advertisements and program promotions, and logging previously aired ad spots. Affiliates trafficked local advertising via logfiles sent over the Internet to a Novar management system located at The WB's corporate offices, that handled trafficking, programming feed dissemination and local insertion to individual affiliates. All programming provided by the service was distributed to WB 100+ affiliates via a centralcasting hub based at the California Video Center in southwestern Los Angeles (near Los Angeles International Airport).
