Growth of Big Data

Over time big data has grown in size and there are many reasons for this. More data is being recorded because more and more people are producing data for example from their mobile phones. Technology is exponentially improving and more and more people are using up to date technology which can produce a wide range of big data. The increased use of social media such as Facebook has greatly contributed to the amount of big data there is. There now exists smart software which can make sense of unstructured data and organise it to make sense to be used.

An example of how fast big data is growing is  Facebook now generates 500+TB of data every day when 30 years ago 200MB was considered a lot of data. An idea of how much it will increase in the future is that 90% of all data was generated in the past 2 years.
