Could This Company Berkshire Owns a 37% Stake in Become the Google of Audio Advertising?

SiriusXM, in which Berkshire Hathaway owns a 37% stake, has partnered with YouTube to become the exclusive advertising representative for YouTube's U.S. audio advertising inventory. This deal could become a meaningful revenue growth engine for SiriusXM, similar to how Google dominates search advertising. The global podcast advertising market is expected to grow from $28.5 billion in 2026 to $38.5 billion by 2030, with SiriusXM's advertising revenue already showing steady progress.
