Halt and Catch Fire season three TV billboards...

Following a much improved sophomore season, AMC's 1980s-set tech drama Halt and Catch Fire returns for a third season this August.

Scoot McNairy, Kerry Bishé, Mackenzie Davis and Lee Pace are all back trying to shape the future of the competitive personal computer industry, the brave new worlds of online gaming, cyber communication and the early days of the internet, with Mutiny moving from Texas to the big leagues of Silicon Valley in the mid-80s.

This season three billboard was first spied above La Brea Avenue on July 29, then later along Melrose Avenue on August 3, 2016.

Fans of the AMC show can also check out these previous season promo billboards for Halt and Catch Fire.

This critically-acclaimed series about a bunch of underdogs really does embody this season's tagline that 'Great minds don't always think alike'.
