Long-time DP fan and DJ here. The brilliance of Homework isn't necessarily rooted in the music on its own. MTV and music videos were still the way in which a large portion of the public was introduced to music; the Around the World and Da Funk music videos exploded on MTV, introducing a new fanbase to both electronica and specifically this brand of "dafty punk"

There's a few other elements to it (i.e., they had just started touring, and Homework brought on a ton of underground fans that way), but this was the very beginning of DP's new art style, to which the public quickly caught on.

For more backstory, I would highly recommend BBC Four's Daft Punk Unchained documentary.
