Connected TV revenues were a major piece of that gain. Total video -- including CTV -- now represents a 30% share of all Trade Desk business, while mobile has a 40% share.

In an earnings call on Monday, Jeff Green, founder and chief executive officer of The Trade Desk, said: “We have nearly 10,000 CTV advertisers on our platform, up over 50% compared to last year.” He added that through the first half of 2021, brands spending more than $1 million in CTV on its platform has already doubled year-over-year.

Net income grew to $47.7 million, from $25.1 million a year ago.

A year ago -- amid a major pause in video and other media ad spending due to the COVID-19 pandemic -- The Trade Desk had a 13% decline in revenue to $139.4 million from the 2019 period.

The Trade Desk says its push for an industry-wide identify ID graph -- Unified ID 2.0 -- continues.

It recently added ad agency holding companies Interpublic Group and the Omnicom Group, TV/entertainment company AMC Network, ad-technology company Blockgraph, and advanced advertising company OpenAP.

Trade Desk expects third quarter financial results to post at least $282 million in revenues.
