In marketing, product bundling is offering several products for sale as one combined product. It is a common feature in many imperfectly competitive product markets. Industries engaged in the practice include telecommunications, financial services, health care, and information. A software bundle might include a word processor, spreadsheet, and presentation program into a single office suite. The cable television industry often bundles channels into a single tier. The fast food industry combines separate food items into a complete meal. A bundle of products may be called a package deal, a compilation or an anthology.
