SILICON VALLEY The Complete Fourth Season - [Blu-ray] Change is in the air in Season 4 of Silicon Valley as the Pied Piper guys pursue their video-chat app, PiperChat, but Richard (Thomas Middleditch) has a hard time letting go of his dream to put his algorithm to better use. As Dinesh (Kumail Nanjiani) flirts with notoriety while Gilfoyle (Martin Starr) looks on in amusement, Erlich (T.J. Miller) searches for his next big break, Jared (Zach Woods) attempts to pivot with the company, and Big Head (Josh Brener) enters the world of academia. Over at Hooli, Gavin (Matt Ross) finds himself threatened by Jack Barker (Stephen Tobolowsky), while Monica (Amanda Crew) struggles to bounce back at Raviga after her fallout with Laurie (Suzanne Cryer). Sharp, irreverent and hilarious, Silicon Valley continues to lambast the self-important world of tech in a season that finds the Pied Piper guys looking to leave their mark, even as they continue to fumble along the road to success. 10 episodes. Widescreen; Soundtrack: English.
