By 2011, Yahoo had expanded its focus to include original content, as part of its plans to become a major media organization. Veteran journalists (including Walter Shapiro and Virginia Heffernan) were hired, while the website had a correspondent in the White House press corps for the first time in February 2012. An Amazon-owned marketing data collection company (Alexa) claimed Yahoo! News one of the world's top news sites, at this point. Plans were made to add a Twitter feed. In November, 2013, Yahoo hired former "Today" Show and "CBS Evening News" anchor Katie Couric as Global Anchor of Yahoo! News. She left in 2017.
