In internet history, credit for the initial concept that developed into the World Wide Web is typically given to Leonard Kleinrock. In 1961, he wrote about ARPANET, the predecessor of the internet, in a paper entitled "Information Flow in Large Communication Nets." 

According to the journal Management and Business Review (MBR), Kleinrock, along with other innovators such as J.C.R. Licklider, the first director of the Information Processing Technology Office (IPTO), provided the backbone for the ubiquitous stream of emails, media, Facebook postings and tweets that are now shared online every day.
