Abstract
As its name suggests, big data, which gives an idea of the data size, contains other mysteries behind it. Indeed, besides its size, its speed and diversity are also highlighted by researchers. For this reason, it is suggested that it cannot be studied with traditional statistical methods. Due to its conceptualization as a new type of fuel, it attracts attention of both businesses and researchers. In this study, statements on big data of the first 250 companies ranked by ISO-500 list for the year 2019 are examined and classified in terms of perceptions of big data and purpose of usage. However, due to limited amount of data obtained, the research has a descriptive and exploratory nature. According to the findings from the qualitative research, it can be stated that most of the big companies, except for a few, are at the stage of development or discussion phase regarding collection, use, and analysis of big data and its’ inclusion in business processes and marketing stages. The limitations of the study include limited amount of texts collected through companies' subjective self-reporting.
