Five months after Bill Demas stepped down as CEO, demand-side platform (DSP) Turn Tuesday filled the void, naming ad technology vet Bruce Falck CEO.

Falck was COO of Yahoo's BrightRoll unit, and before that was a long-time Google executive who helped build seminal ad units Invite Media and the Google Display Network.

Turn, which began as a digital audience ad network founded in 2006, is part of the seminal group of early DSPs that developed the bidding technology that helped create the modern day programmatic media marketplace. The company never explained the reasons for Demas’ departure, but some publications speculated part of the reason was that Turn was experiencing financial problems.

In Tuesday’s announcement, Founder and Chairman Jim Barnett said Falck was the ideal candidate to lead Turn’s next phase, specifically citing his role building Google’s display network, DoubleClick Bid Manager and AdX.
