The ALS Ice Bucket Challenge was started to raise awareness and funds for ALS/Lou Gehrig's disease. It involves dumping a bucket of ice water on one's head and challenging others to do the same within 24 hours, or donate to ALS research. The challenge went viral on social media in 2014, with many celebrities participating. It significantly increased donations to ALS associations, with $98.2 million donated from July to August 2014 compared to $2.7 million the prior year. The challenge also dramatically grew visits to ALS association websites and the Wikipedia page on ALS.
