Knowing What We Know • An Ethnographer Looks at SNA • John McCreery • Sunbelt, March 2012
The Goal • To better understand the relationship between social network analysis (SNA) and historical and ethnographic research (HER)
ArchivalData Desk Research SNA Interviews A Work in Progress Credits from the Tokyo Copywriters Club Advertising Copy Annual (1981, 1986, 1991, 1996, 2001, 2006), manually entered into a Filemaker Pro Database The starting point is a set of six 2-mode multiple edge affiliation networks that contain a total of 7018 creators connected by 27, 314 roles to 3,634 award-winning ads, analyzed using Pajek Many of the high-centrality creators are authors or frequently interviewed in a large and active trade press—several hundred pages per month of coverage in monthly magazines, numerous new books each year, and now Websites and blogs as well. Interviews with high-centrality creators using results of SNA and Desk Research as stimulus material

Akiyama Sho(Autobiographical Statement Found Online) • Born in Tokyo in 1936, he graduated from the Rikkyo University Faculty of Economics in 1958, and joined the Kodansha advertising department the same year. He joined Light Publicity Ltd. in 1964, and he is currently president of that firm. His work involves advertising production, including both graphic and film direction, and copywriting. He cherishes the words of Takashi Nakahata, "The bullet has a beautiful form because it speeds to its target."

Time Matters(It Really Does) • 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.

A Special Relationship Sasaki Hiroshi Anzai Toshio
そうだ京都、いこうThat’s It, Kyoto. Let’s go. • One of the most successful and longest-running campaigns in Japan’s advertising history. • Sasaki and Anzai worked together on this campaign. Sasaki was younger and a copywriter, Anzai older and a CM planner. • Anzai tells me a story about this collaboration...
In 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.*
