Newgrounds is an American entertainment website founded by Tom Fulp in 1995 and owned by Newgrounds.com, Inc. The site hosts user-generated content such as games, films, audio, and artwork. Fulp produces in-house content at the headquarters and offices in Glenside, Pennsylvania.
In the 2000s, Newgrounds played an important role in Internet culture, and in Internet animation and independent video gaming in particular. It has been called a "distinct time in gaming history", a place "where many animators and developers cut their teeth and gained a following long before social media was even a thing", and "a haven for fostering the greats of internet animation".
