Greeting cards are pieces of paper[paper?:paper sample maker cutting machine] or cardboard upon which photos, drawings, and a verse of cheer, greeting, celebration, condolence, etc. have been printed or engraved. Greeting cards are decorated with a variety of images and include messages to appeal to diverse audiences, sentiment, and occasion to be remembered. Greeting cards are easily made at home using pen and paper or software sold by greeting card and other companies. Despite the availability of electronic cards, the greeting card industry continues to sell cards in retail store in huge numbers. Over 1,500 greeting card manufacturers sell an estimated seven billion cards each year. Each household receives an average of 80 greeting cards annually.
Research has pushed large greeting card companies to expand traditional product lines and offer cards for pets, step-siblings, divorce, weight loss encouragement, company lay-offs, and more. Some smaller greeting card companies specialize in the production of cards that appeal only to one or two specific markets. Greeting card companies require a diverse talent pool in order to produce commercially-successful greeting cards.
