An Oscar party is any of the various parties, usually hel by entertainment-media corporations, immediately following the broadcast of the Academy Awards ceremony. Some sponsors, such as Vanity Fair magazine, are known for holding such a party year after year, and the influence of the sponsor can be roughly measured by the caliber of the stars that attend their party. In recent years, many of these events have adopted a charitable theme, such as the Elton John AIDS Foundation After-Party.
