The digital era of going viral

If you have ever studied the science of cross pollination, you would realize that the plants that use this mechanism to reproduce need certain agents to achieve this goal. These agents are mostly birds and insects and it is the flowers that have certain features; colourful, sweet scented and sometimes contain nectar that that are pollinated. When the birds and insects settle on the plants and feed on them, they carry pollen on to the next plant; fertilization takes place, leading to reproduction. If you are to explain this in the language of marketing, you would say the pollen has gone viral.
