CTV platforms.
Overall, the CTV ad landscape is strongly dominated by three companies:YouTube, Hulu and Roku.YouTube is the biggest recipient of CTV ad spending, accounting for 40% of our total CTV ad spending estimate, while Roku and Hulu collectively account for an additional 30%. About seven in 10 total US CTV ad dollars go to these three companies.
Meanwhile, CTV programmatic video ad spend will grow considerably to $6.26 billion by 2021. Most CTV ad spending
will be programmatic, but just a small portion of total programmatic spending goes to CTV. We forecast that in 2019, CTV would represent 6.1% of total programmatic display ad spending, and in 2021, CTV will take in 8.1% of all programmatic display spending.
Ad spending projections from multiple research firms vary considerably, but one thing is clear: Investment in connected TV (CTV) is soaring. For the foreseeable future, CTV ad spending will increase by double digits annually. In our first-ever forecast for US CTV ad spending, we estimate that it will hit $14.12 billion by 2023, accounting for 7% of total digital ad spending and nearly 5% of total media ad spending.
