Going ‘direct to consumer’ offers a lot of benefits for media owners like Discovery, but building a direct to consumer business is hard says Discovery’s vice president of digital David Fisher. Apps and streaming services have to be updated to match the progress of technology, while content has to be chosen which can support a subscription service. In this interview, Fisher also discusses the risks of operating in the app ecosystem, and why he thinks scale is the biggest challenge facing addressable TV advertising in Europe.
