History

What happened in 2004

The United States entered 2004 with troops fighting in Iraq and Afghanistan and a presidential campaign already taking shape. President George W. Bush made national security and his conduct of the wars central to his reelection case, while Massachusetts senator John Kerry emerged from the Democratic primaries as the challenger. News from Iraq, including the Abu Ghraib prisoner-abuse photographs and the battles in Fallujah, kept the war at the center of public debate. On November 2, Bush won a second term with 286 electoral votes and 50.7 percent of the popular vote.

Technology was moving from the desktop toward a more social internet. NASA's twin rovers Spirit and Opportunity landed on Mars in January and began missions that would last far beyond their planned 90 days. On February 4, Harvard student Mark Zuckerberg and classmates opened TheFacebook to students on their campus. Google introduced Gmail on April 1 and sold shares to the public in August, while Apple expanded the iPod line and its young iTunes music business.

Sports supplied the year's most cathartic American story. The Boston Red Sox came back from a three-games-to-none deficit against the New York Yankees, then swept St. Louis to win their first World Series since 1918. The Detroit Pistons upset the Los Angeles Lakers in the NBA Finals, and the New England Patriots won a second Super Bowl in three seasons. The year ended with a catastrophe far from US shores: a magnitude 9.1 earthquake off Sumatra on December 26 sent tsunamis across the Indian Ocean and killed more than 220,000 people in 14 countries.

    Google Introduces Gmail by Invitation

    Google announced a free email service offering one gigabyte of storage, far more than leading competitors offered at the time. Gmail began as an invitation-only beta product and organized related messages into conversations, helping make webmail a central part of Google's expanding services.

    Massachusetts Begins Issuing Same-Sex Marriage Licenses

    Massachusetts became the first US state to allow same-sex couples to marry after the state's highest court ruled in Goodridge v. Department of Public Health that excluding them violated the state constitution. Couples began receiving licenses on May 17, the 50th anniversary of Brown v. Board of Education.

    Former President Ronald Reagan Dies at 93
