Dex Media is an advertising company formed when the two main firms in the domestic yellow pages industry, SuperMedia (SPMD) and Dex One (DEXO), merged.
Some other social media companies that have seen large gains during the past year include Snap Interactive (OTC: STVI), PeopleString (OTC: PLPE), and SuperMedia (NASDAQ: SPMD).
My company became activist with SPMD in the summer of 2012 when we filed a Form 13D wherein we recommended that its board consider a merger with its largest competitor (DEXO.) I was very pleased to see that within short time after our 13D filing the board agreed and ultimately signed a merger agreement.
