Alphabet, the parent company of Google, continues to dominate as the world’s leader in digital ad revenue. In 2019, the company generated nearly $162 billion in revenue, an increase of more than 18%, along with more than $34 billion in profit. But Alphabet, along with other big tech companies, remains under regulatory scrutiny for some of its business practices. In Europe, the company is appealing rulings that found that it restricted competitor’s ads and broke data privacy laws. And in the U.S., regulators are investigating allegations of similar violations. The appointment of Sundar Pichai, the former Google chief, as Alphabet's CEO last December represents a new stage for the Silicon Valley giant; many expect Pichai to impose greater financial discipline—particularly on bold but money-losing "other bets," such as its efforts with self-driving cars and health tech.
