Compu-Global-Hyper-Mega-Net is Homer's Internet company from the episode "Das Bus". The company's headquarters is the dining room of 742 Evergreen Terrace. It is never made clear what the company sells or offers; however, Microsoft's Bill Gates still "buys out" the company.
Homer, having apparently never heard of the internet, researches and decides to set up his own internet company, initially copying the Flancrest Enterprises name before settling on his own baffling "Compu-Global-Hyper-Mega-Net".
It is never revealed what Compu-Global-Hyper-Mega-Net does, nor whether it is successful, however, it soon attracts the attention of Microsoft CEO Bill Gates.
Gates visits the Simpsons and proposes to buy their business depsite admitting he has no idea of the website purpose. Marge and Homer quickly discuss the proposal and "reluctantly agree" to sell to Gates.
Gates then instructs the goons he has brought along with him to 'buy out' the Simpsons, upon which they proceed to smash the office and destroy Homer's things.
Marge and Homer, who are trapped in a corner of the living room, question Gates about this to which he replies that he "didn't get rich writing checks". Gates then laughs menacingly as the Simpsons office continues to be destroyed in the background.
