Ad Age lists the top 10 viral videos for the week of Dec. 7.

A gaggle of Google videos have hit the chart as new entries.  If you missed it, the most compelling is the painstakingly produced video for Google Chrome.  It uses a clever offline approach to showcasing the web browser’s online features.  The others are for Google Goggles (juicy product, bone-dry video) and Google real-time and local search (needed this query: smell smoke in my house ).  A fourth new entry has a worthy cause raising awareness for the UN climate talks in Copenhagen but as a Danish state ministerial production has all the trappings of an overfunded, under-produced government video.

A nifty video that Ad Age has as a returnee to the chart is Samsung’s Extreme Sheep Art promoting its LED HDTVs.  For videogames, Microsoft Natal is still drawing enough eyes to stay frozen in the middle of the pack, while Activision’s Tony Hawk: Ride with hotdog Tillman just barely hangs on at the bottom.

Ad Age’s chart includes number of views for the week and percentage change in views for videos that stayed on the chart.  The list is compiled by Visible Measures.
