At launch, Google’s new subscription service YouTube Red competes most directly with premium music streaming services, also offering ad-free videos

YouTube’s augmented revenue model re-boots incentives for native talent to produce content for the platform, and will also widen its appeal for established content producers

Participation in online activities is up across the board, but digital media data shows spend on ebooks and digital music struggling, with the latter being heavily impacted by the rise of unlimited streaming models such as Spotify

The story of mobile's surge continues, with almost a half of e-commerce transactions and a third of search and display ad spend now going to mobile.
