According to the report, the auto giant's marketing executives "determined their paid ads had little impact on consumers."
GM marketing chief Joel Ewanick told the Journal that the automaker "is definitely reassessing our advertising on Facebook, although the content is effective and important."
The automaker will continue to use free options on Facebook.
The largest American automaker spends about $40 million to maintain Facebook presence, the Journal reported, with about $10 million in paid ads.

This is interesting in that in a few days Facebook with have their IPO - initial public offering of stock - which is expected to raise a significant amount of money for Facebook.  But, Facebook's primary source of revenue is advertisements - and if GM pulls out - and others as well, it will make a big difference in the value of Facebook.  If "their paid ads have little impact on consumers" in GM's case, it may be true on other consumers as well!!
