Griffiths (pictured) joined Barb as head of strategic developments in 2016, working with research agencies and broadcasters to help deliver new services, such as implementing the next phase of Project Dovetail, an audited cross-device measure that will integrate Barb’s panel data and online TV viewing census data. Prior to joining Barb, she was previously head of research at Guardian News and Media.

Reporting to Griffiths, Whelpdale will be responsible for helping agencies, advertisers and broadcasters use Barb data. He will also work with broadcasters to help them to participate in the organisation’s new reporting services following the launch of Dovetail Fusion. His appointment follows the departure of head of insight Joe Lewis, who left the organisation at the end of 2017.

Whelpdale joins from The Walt Disney Company, where he held the role of senior insight manager for media sales and partnerships.

Justin Sampson, chief executive at Barb, said: “In the 18 months since her appointment, [Griffiths] has become a key member of Barb, taking the lead on delivering our key projects.” He added that Whelpdale’s appointment “further strengthens the team for what is an important year ahead.”
