He came to wider attention for his work in the United States on The Daily Show with Jon Stewart as its senior British correspondent from 2006 to 2013. Oliver won three Primetime Emmy Awards for writing for The Daily Show and was its guest host for an eight-week period in 2013.

He has received widespread critical and popular recognition for his work on the series, whose influence over US culture, legislation, and policymaking has been dubbed the "John Oliver effect". For his work on Last Week Tonight, Oliver has won thirteen Emmy Awards and two Peabody Awards and was included in the 2015 Time 100, being described as a "comedic agent of change...powerful because he isn't afraid to tackle important issues thoughtfully, without fear or apology". Many have described Oliver's work as journalism or investigative journalism, a description Oliver rejects.
