Albert Yu is the author of theSignal, a biweekly publication covering Connected TV, streaming monetization, and ad technology. He works at ElementalTV on the ad server infrastructure that watches how money actually moves through CTV auctions in real time. theSignal is written from that vantage point. Earnings calls describe one business, the bid stream describes another, and the interesting questions live in the gap between them. Every claim in his writing is earned from something observable in the system. He covers what the trade press misses, on purpose.
