When:
Lookups spiked on September 25, 2014.
Why:
Attorney General Eric Holder announced his departure from government, and Derek Jeter played his last home game at Yankee Stadium. Many articles and comments about their careers used the word legacy.
For example, a headline on ESPN's blog reads: "Jeter's legacy: consistency, reliability." A headline at TIME.com reads: "Eric Holder Will Leave A Legacy of Civil Rights Activism."
Legacy means "something that happened in the past or that comes from someone in the past." It comes from the Latin word that means "to send as an emissary" or "to bequeath".
