The formulas for Entourage and Silicon Valley are pretty similar: A tight-knit group of five guys trying to make it in the world while overcoming obstacles along the way. Yes, one crew lives a fantasy Hollywood life while the other grinds it out in the Silicon Valley tech world, but many of the story lines are interchangeable. So much so in fact that if they were on the phone with each other, one might not be able to tell the difference between the shows.
