WORD TRENDS
Most people are now happy to spread viral infections to their friends， family， and work colleagues. They do so not by sneezing on them but by forwarding emails， images， or videos that have amused or intrigued them. The influence of this word-of-mouth publicity on brand awareness and sales is enormous， and one of the commonest compounds of viral is viral marketing. There are now entire companies， known as viral agencies, devoted to creating potential viral hits for businesses. See also MEME.
