The short version

Brian Wieser predicted on November 26, 2018: “Pivotal's Wieser revises ad outlooks upward, citing strong economic indicators — global advertising will grow faster than previously forecast through 2019.” Verdict: Partially right. GroupM (which Wieser later joined) downgraded the same forecast 4 months later as USD strength and macro caught up. 2019 ad growth came in below the upward revision.
