Count Down Memorable Videos of the Year

We'd give you chocolates with it if we could: This week marks the launch of our advent-style calendar counting down some of the most memorable videos of the year on YouTube. This sponsored collection, presented by Samsung U10, will reveal one new popular video each day throughout the month of December.

Without giving too much away, you can expect to see some well-known YouTube videographers on the countdown, along with breakout viral videos and a selection of the year's biggest pop-culture phenoms and memes.

During December, we'll be adding playlists to the channel to dig a little deeper into YouTube's content categories -- because we know that a video doesn't have to have millions of views to make an impact.

So check out the countdown as it unfolds, and see if your favorite clips or personalities are featured. Definitely let us know in the comments what your video of the year would be, whether it's a blockbuster clip or one that simply made an impression on you. With a limit of 31 videos in the countdown, we know it only just scratches the surface of this incredible time on YouTube.

A Live Stream to Save Lives: Alicia Keys and YouTube Team Up to Fight AIDS

It's no secret that AIDS is one of the deadliest diseases facing our world today. Since the beginning of the epidemic, almost 60 million people have been infected with HIV and 25 million people have died of HIV-related causes. But did you know that some of those hardest hit by AIDS are children? The disease has killed over 2 million children, and in sub-Saharan Africa it has orphaned close to 15 million.

That's why, today, on World AIDS Day, we're partnering with Alicia Keys and her organization, Keep a Child Alive, to present a live-streamed benefit concert at 8 p.m. (ET). We're also encouraging everyone to donate $5 to provide the life-saving medication, support, and orphan care to keep these children alive. Learn more from Alicia herself about this important effort:



You can make a difference today. Please tune in here at 8 p.m (ET) to watch Alicia Keys and donate to help save the lives of millions of children living with HIV/AIDS.

Join Morgan Freeman to Bring Human Rights Work to Light

YouTube can be a powerful tool championing the rights of individuals and promoting free expression. This month, during International Human Rights Day, we're partnering with Morgan Freeman and Amnesty International to encourage you to become advocates for equality and justice, through Video Volunteers.

Here's how you can help. Create a video about the nonprofit of your choice working on a human rights issue that you care about -- it could be genocide, human trafficking, refugee protection, gender equality or something else -- and submit it to the Video Volunteers channel by December 21. Amnesty International and Freeman, who plays legendary crusader Nelson Mandela in the upcoming movie Invictus, will select three videos to appear on the YouTube homepage at the end of the month. Hear more from Morgan about the importance of taking up this cause:



This is your chance to help citizens around the world who often can't help themselves and to bring the vital work of human rights organizations to light. Join Morgan Freeman to protect the rights of these individuals at www.youtube.com/videovolunteers.

Spaghetti Western Viewing Party Tonight

There are two kinds of people in the world: those who watch Spaghetti Westerns by themselves and those who watch them with their YouTube buddies.

If the latter sounds like fun, join us for a live viewing party of "The Good, the Bad and the Ugly" at 6pm PT in the Screening Room. To the right of the player, you'll see a Twitter feed collecting real-time tweets from other fans watching the film.  If you want to contribute to the conversation, just log in to your Twitter account through the gadget and send your tweets, being sure to use the default hashtag, #screeningroom.

We'll be right there with you, sharing our own thoughts on one of the best westerns of all time. See you there!

YouTube Community Gives Thanks to Those That Help the Hungry

Earlier this month, as part of YouTube Video Volunteers, we asked you to create a short video for the nonprofit organization of your choice tackling the issue of hunger in America. Today, we're featuring the top three submissions, chosen by our partner Feeding America and curator David Arquette, on the YouTube homepage in honor of Thanksgiving, to recognize the important work that is being done to feed those in need.

We were surprised and excited by the range of videos submitted. For example, partner bigedude33 penned an original song about the Food Bank of Central New York, while HavilahTower lent her voice to the Capital Area Food Bank in Texas:



Filmmakers like CassieJaye and nsmith345 powerfully depicted the faces of American citizens being helped by their local food pantries, while vlogger Shawn Ahmed went inside the L.A. Regional Food Bank to demonstrate exactly how they provide support to the Los Angeles community:



To view all Video Volunteer submissions for this month, please visit www.youtube.com/videovolunteers. And be sure to check the channel again next week when we kick off another Video Volunteers round, focusing on human rights, with curator Morgan Freeman.

Giving Thanks

Last week, ABC News' Good Morning America asked you to share videos about what you're thankful for. In the days leading up to Thanksgiving, many of you have answered their call and invited others on YouTube to create their own "thankful for" lists.

You're thankful for lots of stuff, including your families, your good health, and the everyday things in your life that often go unnoticed. Some of you even shared deeply personal stories about why you're grateful.

We're running a special spotlight on the homepage today to showcase some of these videos, and this morning, Good Morning America featured a selection on television in honor of today's holiday. Take a look here.

Happy Holidays -- with thanks.
