Final answer:
The Internet originated from the collaborative efforts of military and academic researchers, leading to ARPANET, which established the basis for today's communication protocols and technologies.
Step-by-step explanation:
The development of the Internet has its roots in the collaboration between military and academic research, which was spearheaded by the United States Department of Defense during the Cold War and resulted in the creation of the Advanced Research Projects Agency Network (ARPANET). This network allowed enabled military and academic researchers to communicate on a distributed network system. It was the precursor to the Internet, fostering the development of essential protocols and technologies like email and hypertext that we rely on today. The first computer networks like SABRE and Licklider's 'Intergalactic Computer Network' concept were instrumental in setting the foundation for ARPANET's success. The impact of the Internet on global culture and communications has been profound, changing the way information is shared and accessed worldwide.
