It's the 1990s and Joe and Gordon have built their internet company. The problem is, only one of them is really running it.

Watch a Sneak Peek of the Season 4 Premiere.

As the World Wide Web flourishes, Gordon can see the competition on his doorstep... literally. But Joe being Joe, he has his eyes set on something new -- building the best web browser. Downstairs, alone and surrounded by Post-Its, Joe insists that they can't give up on the browser project. Gordon points out that after three years he's still in the basement, alone, while the company is under attack from competitors.

How will Joe respond when Gordon asks him to come upstairs, abandon the browser project and help him run the company? Find out in a sneak peek the fourth and final season, which kicks off with a two-hour premiere on Saturday, August 19 at 9/8c.
