Affinity Labs is a company that builds social networking sites for niche groups such as firefighters, police officers, nurses and the Armed Forces. In January 2008, Affinity Labs was acquired by Monster Worldwide for US$61 million.
Affinity Labs sites have over a million registered members, as of January 2008. PoliceLink, aimed at law enforcement personnel, is one of Affinity Labs' most active sites with over 717,000 unique visitors per month. Other sites include: SalesHQ, ArtBistro, TheApple, FireLink, NursingLink, InsideTech, GovCentral, IndiaOn, Excelle, AllHealthCare, and the European communities, HMForces.co.uk, ProNurse, and WerPflegtWen.
In 2008 after Monster acquired Affinity Labs, it then bought a French military website, Armees.com for an undisclosed fee, then transferred the site to its Affinity Labs social networking vertical.
Affinity Labs still successfully operate across North America but in March 2012 it shut down its European operations. Despite HMForces.co.uk being its most successful vertical, and having shared resources with Military.com, the global recession did not assist its longevity. HMForces.co.uk still has a strong presence on social networking sites to this day, evidence of its popularity. Further references to this military vertical can be found on UK e-commerce sites, and there is also a HMForces blog still surviving despite it not being updated regularly.
2010-12, the current President of Military Advantage and Vice President of Monster Worldwide, former Navy Admiral Terry McCreary oversaw the military Affinity operations in Europe which had a product manager in London reporting to the former Admiral in the US.  However, this operation was closed down in 2012.
