Produced by combining six 2-mode networks, simplifying the result, projecting the 1-mode creators network in which line values are the numbers of projects on whichpairs of creators have both worked, and then performing p-Core analysis. (See Appendix 1 for details).

• Age MattersMost super stars have had long successful careers. Except for the occasional supernova—Tada Taku, who burst on the scene with an unprecedented triple Grand Prix is an example, Itoi Shigesato was another — it takes time to become a super star.
• Sampling MattersTo appear in our network, our stars’ glory days had to have been within the years our sample spans (1981-2006). Many historically famous names do not appear because their glory days were in the 1960s and 70s.

In ConclusionIn Conclusion• SNA makes it possible to focus quickly and precisely on key
players in a network too large to grasp with the naked eye alone.
• SNA can surprise us, identifying key players who were off our radar, Iwasaki Shunichi (1947), for example.
• Historical and ethnographic research (HER) adds depth to our understanding of important relationships and reminds us that time matters when examining archival data.
• HER can also surprise us, by identifying relationships that may not seem so important in purely SNA terms but may be very important, indeed, in how the actors we study perceive their networks.*
