The Graphic Design Olympics (2004) by
Michael Bierut at Design Observer, and another short comparison of various Olympic icons. Interesting recent work includes pictograms developed for the 2008

The use of pictograms in history and in modern design is an established field of study, with major works by Henry Dreyfuss (
Symbol Sourcebook),
Otl Aicher,
Otto Neurath,
Paul Rand, Edward Tufte, and others.
A few sentences on the subject can only be inadequate. For more info, see
Navigating Today’s Signs: An Interview with Mies Hora by Steven Heller and
Critical Wayfinding by Ellen Lupton and J. Abbott Miller. "Modern Hieroglyphs" in

pdf) makes a really cool use of pictograms in explaining pictograms in design and history.
Update: Slate has 6-part series on
The Secret Language of Signs, which includes
why signs are better now than they've ever been, why the signs in
Penn Station are so confusing, how smarter signs could make
London easier to navigate, and the international war over
the exit sign.
