Alphabet, the second-largest market-cap stock, celebrated Friday the 12th anniversary of its initial public offering as Google.
CNBC looked at the company's growth over the years to see how exponential it's been.
Aug. 19, 2004 — Google goes public at $85 a share, giving the company a market cap of $23 billion. Shares leapt 18.04 percent in the first day of trade, versus the 8.9 percent average first-day performance of this year's IPOs.
Since the IPO, those Class A shares, now traded under the ticker GOOGL, are 1,779 percent higher on a split-adjusted basis at $798.87 a share intraday Friday. That's a market cap of about $543 billion, just shy of Apple's roughly $588 billion market capitalization.
The deal size for Google's IPO was $1.7 billion. In comparison, that of Facebook was $16 billion, almost eight years later in 2012.
April 3, 2014 — Class C shares begin official trading.
Aug. 10, 2015 — Google announces a restructuring plan to make it the subsidiary of a new parent company, Alphabet, which assumes the tickers of both existing share classes.
Annual revenue last year was nearly $75 billion, up from $66 billion in 2014 and more than 20 times annual revenue in 2004 of about $3.2 billion. Last year's profit of $16.3 billion compared with profit of less than 400 million the year Google went public.
