Leonard Nimoy had a now-infamous argument with Gene Rodenberry over whether Spock should wear that IDIC necklace in 1969. A symbol that would become the emodiment of Federation ideals and one of the few constants in the Star Trek universe was scorned by Nimoy as a commercial ploy to produce a new image the franchise could sell. (And it was, of course; that's my point - commercialization isn't intrinsically bad. Today IDIC is arguably more recognizable than the Federation flag.)

For what it's worth, I refused to watch the Next Generation for Two Years because "that's not Star Trek." I'm glad I changed my mind! ♥
