This week and next thousands of viewings will be held around the world of the Rebbe's Farbrengen of Yud Alef Nissan Shnas Hashmonim.

A search of the New York Times' archives from that period turned up this ad.

Dozens of families will be hosting their friends for viewings of the newly-released video of this Farbrengen, including over ten in Crown Heights alone. Host your own viewing at http://farbrengenchallenge.com/viewings
