Virtual Pharma companies

Past week after coming from a 3days trip from Luck now life was bit hectic and during the weekend was reading about virtual pharma and biotechnology service providers, In the past decade we had quite huge number of virtual companies in Bio-informatics related Drug Discovery (early 90s) to the completion of human genome project in year 2000 and then from initial 2000 we had more companies blooming up in the field of knowledge process outsourcing (Market, competitive and business intelligence) and CRO's , overall these virtual companies have become backbone for pharma industry for lead generation to drug's brand equity.
