Viral marketing can be less expensive than traditional marketing campaigns, yet grow faster — especially with the help of social networks as a "force multiplier." Since it can receive so much traffic in a short time, it can also lead to mainstream media attention. Social media can also cause viral marketing efforts to misfire, as messages are altered, misconstrued, considered spam or called out for missing the mark. Viral marketing success can also be hard to measure.
To save time and effort, a person can group two or more of their passive activities into one larger activity, provided they form an "appropriate economic unit." When a taxpayer does this, instead of having to provide material participation in multiple activities, they only have to provide it for the activity as a whole. In addition, if a person includes multiple activities into one group and has to dispose of one of those activities, they’ve only done away with part of a larger activity as opposed to all of a smaller one. 
Most forms of marketing, viral strategies among them, benefit greatly from research into the trends and habits of consumers. A market researcher reads existing consumer data and conducts original research to determine what consumers want and how to reach them. These tasks demand great attention to detail, computer literacy, and strong communication skills.

Whereas Kaplan, Haenlein and others reduce the role of marketers to crafting the initial viral message and seeding it, futurist and sales and marketing analyst Marc Feldman, who conducted IMT Strategies' viral marketing study in 2001,[citation needed] carves a different role for marketers which pushes the 'art' of viral marketing much closer to 'science'.[23]

There is debate on the origination and the popularization of the specific term viral marketing, though some of the earliest uses of the current term are attributed to the Harvard Business School graduate Tim Draper and faculty member Jeffrey Rayport. The term was later popularized by Rayport in the 1996 Fast Company article "The Virus of Marketing",[12] and Tim Draper and Steve Jurvetson of the venture capital firm Draper Fisher Jurvetson in 1997 to describe Hotmail's practice of appending advertising to outgoing mail from their users.[13] An earlier attestation of the term is found in PC User magazine in 1989, but with a somewhat differing meaning.[14][15]
