- Pomona College, if not the Trope Namer, is at least the Trope Codifier, as seen here
- Star Trek had a Pomona graduate and member of the society Joe Menosky write several episodes of TNG and Voyager. The trope caught on with the other writers, to the point that the number 47 has a page on on the Star Trek wiki.
- J.J. Abrams picked this up and uses it in his series, most prominently in Revolution and Fringe. He's also brought it to Star Wars, where it's now being used over 1138.
- The protagonist of the Hitman series.
- Averted by HK-47 from Knights of the Old Republic, who is named after the AK-47. Same goes for the multitude of fictional guns with 47 in the name.
- As most (all?) the writers of the League of Intergalactic Cosmic Champions were Star Trek fans 47s were a big in joke there too.
- The Wonderbolts of the Reading Rainbowverse are part of Spec Op group 47.
The 47 Society
As detailed on The Other Wiki here, the number 47 has become an in joke among groups of mathematicians and screenwriters, improbable as the crossover may seem. (it's a prime number, by the way)
