Have 25 years since the birth of the first smile of the kind created with ASCII characters. These "smiles" or smiles in Spain are called emoticons.

These symbols were created at the University of Pittsburgh without any intention. Professor Al Fahlman occurred included in an internal message this smile to highlight the irony of the text.

At present emoticons have evolved through the graphical tools and an increasing number of users who use them as a means to express their feelings, and even welcome to express actions.
