ICT has had an impact on how the marketing and sales department is able to work. Databases make it far easier to store and retrieve information. When a customer uses a Club Card, Tesco puts all of the information about their shopping into a database that contains all of that customer’s spending habits. If Tesco are planning a promotion on cat food they will be able to get a list of all of the customers who have purchased cat food in the last 12 months and send them money-off coupons.
The internet has increased the size of the market to which businesses are able to sell. Many businesses have invested large amounts of money into websites that allow customers to make purchases on-line. Tesco and Sainsburys allow you to choose your shopping on-line and have it delivered to your door at a convenient time.
