Social networking sites such as You Tube and Facebook have been successfully exploited by many consumer product companies for viral marketing campaigns. These campaigns are so named because the transmission of a marketing message through the networks is seen as analogous to the spread of a viral infection in a population.
It can be extremely difficult to identify who is responsible for content spread through such networks, and it is not clear how widely the pharmaceutical industry is using them. A recent search for ‘Champix’ on You Tube (accessed 12 November 2008) identified 46 videos, many of which appeared to be of ordinary viewers describing their experiences with varenicline. It was unclear whether any of these videos were commercially generated. However, the first one identified by the search (http://au.youtube.com/watch?v=Vx7baviT1DQ) linked to a website whose name suggests it is an individual's personal site (http://www.kims-website.info), although it appears in fact to be a commercial site. On the other hand, such networks are also being used for public health purposes, including promoting messages about the quality use of medicines. You Tube also includes, for example, a US Food and Drug Administration (FDA) video discussing potential adverse effects of varenicline.7
Even when listings are clearly commercials, as with a bizarre video on You Tube promoting a new medicine for insomnia, ramelteon, it is not necessarily clear who is responsible for posting them. The video features an insomniac chatting with Abraham Lincoln and a talking beaver over a chess board. These characters also appear in a direct-to-consumer television advertising campaign in the USA. The video was submitted to You Tube in 2006 by ‘lewisusauk’, who said: ‘New Rozerem Ad Campaign. Possibly the best prescription drug ad since the FDA relaxed the rules on drug advertising’. According to a pharmaceutical marketing blog by John Mack (http://pharmamkting.blogspot.com), lewisusauk is a ‘sock puppet - a false identity through which a member of an internet community speaks while pretending not to, like a puppeteer manipulating a hand puppet’.
Apart from disseminating company-generated content, social networking sites also offer opportunities for companies to insert themselves anonymously into conversations between site users through postings and comments on blogs. John Mack says some of the postings about the ramelteon video on You Tube smack of this practice, and ‘are attempting to hijack the conversation by submitting commercial messages (that is advertisements) disguised as genuine comments from ordinary citizens’.
Meanwhile, in the Netherlands, an industry-driven campaign conducted via Hyves (a Dutch equivalent of Facebook) gathered more than 80 000 signatures in only three weeks for a petition aimed at influencing decisions about funding for human papillomavirus vaccines. According to Dr Ruud Coolen van Brakel, Director of the Dutch Institute for the Proper Use of Medicine, it was ‘a very effective way to create public awareness and commitment to a commercial cause disguised as a public health issue’.
Pharmaceutical companies are also seeking to capitalise on medical social networking sites. Pfizer, for example, is reportedly collaborating with Sermo Inc, a web venture based in Cambridge USA, where tens of thousands of doctors discuss diagnostic and treatment issues in anonymous postings. The collaboration allows Pfizer's doctors to ask questions and respond to posts. Members can also rank postings, which will give insights likely to help the company's development of marketing messages. Sermo is said to be in talks with other companies as well. The site earns money by letting clients such as hedge funds monitor doctors’ anonymous conversations and thus gain insight into, say, the popularity of certain treatments. Sermo rewards physicians whose input is highly ranked by other members and plans to offer to pay doctors for participating in its clients’ surveys.8,9
