Did the pentagon invent the internet?

The Pentagon did not invent the internet, but it played a significant role in its development. The initial concept for what would become the internet originated from research funded by the U.S. Department of Defense through the ARPANET project in the late 1960s. ARPANET was the first network to implement the packet-switching technology that underpins internet communications today. However, the internet as we know it was developed later by various researchers and organizations worldwide.
