Earth Hour Day On YouTube

Hi! Everyone, hope you all are fine.
Today in this post I will tell you about YouTube Earth Hour Day. Earth Hour is a global event organized by WWF (World Wide Fund for Nature, aka World Wildlife Fund) and is held on the last Saturday of March annually, asking households and businesses to turn off their non-essential lights and other electrical appliances for one hour to raise awareness towards the need to take action on climate change.

Earth Hour was conceived by WWF and The Sydney Morning Herald in 2007, when 2.2 million residents of Sydney participated by turning off all non-essential lights. Following Sydney’s lead, many other cities around the world adopted the event in 2008. Earth Hour 2011 will take place on March 26, 2011 from 8:30 p.m. to 9:30 p.m., at participants’ respective local time.

And this time YouTube have also taken part on Earth Hour Day by putting a switch on every video page on YouTube website. When someone clicks on that switch, full YouTube video page color goes dark. But to make it dark you have to click on it every time you visit a video page, after one click it doesn’t become default for all video pages. Here is a quick demo

This is Light ON video page, the normal one which we see daily
