The following video is part of our "Motley Fool Conversations" series, in which industrials editor/analyst Brendan Byrnes and technology and media editor/analyst Andrew Tonner discuss topics across the investing world.

In today's edition, Brendan and Andrew discuss GM's recent decision to stop advertising on Facebook. GM will maintain its free Facebook page but will no longer purchase advertising on the site. Brendan thinks this could potentially affect Facebook more than GM, considering that GM is the third largest advertiser in the U.S. While the amount that Facebook is losing from GM is very small -- $10 million -- the bigger risk lies in other companies following GM's lead and taking a harder look at advertising on Facebook. Andrew thinks this might hurt Facebook a bit but won't have a material impact on the company, as there are still a massive amount of people that can be reached on the social networking site.

While GM looks incredibly cheap and like a solid bet to outperform the market over the long term, we've come across a different stock that has us so excited we can hardly contain our investing enthusiasm. This pick has so much promise that we've dubbed it: "The Motley Fool's Top Stock for 2012." We've created a special free report for investors to uncover this soon-to-be rock star.
