In 2015, global programmatic ad spending reached $15 billion and is expected to rise to $33 billion by 2017, with projections indicating that programmatic advertising will account for 63% of all digital ad display spending in 2016. Trends include a move towards programmatic direct buying, enhanced cross-device targeting, and the increasing importance of programmatic TV, while challenges such as ad fraud and brand safety continue.
