When ¡°A History of the World in 100 Objects¡± aired its final episode on Oct. 22, 2010, millions of loyal listeners eagerly tuned in.

The BBC Radio 4 series, on which the current exhibition of British Museum artifacts at the Tokyo Metropolitan Art Museum is based, had charted 2 million years of history with 99 15-minute broadcasts revealing stories behind some of the London museum¡¯s most important historical objects. Naturally there had been much speculation on the 100th artifact. What could possibly represent the advancements and complications of contemporary society to earn a place in one of the largest museums in the world?

It took nine months of week-day broadcasts to reach the milestone, so it surprised some, if not disappointed a few, when it was revealed that the 100th object was a ?30 (?5,415) portable solar-powered lamp and charger.
