A lot has changed since the case of CDC v IBM in 1971 legitimised the use of technology in supporting litigation. In that case, approximately one million documents were scanned onto microfiche and indexed into a mainframe database by a team of 120 paralegals.

As the technology has evolved, so too has the once-common perception that litigation support technology is only applicable to matters where there are very large quantities of documents to be processed or where information in documents has to be identified and extracted rapidly.
