December 12, 1980: Apple goes public, floating 4.6 million shares on the stock market at $22 per share.

In the biggest tech IPO of its day, more than 40 out of 1,000 Apple employees become instant millionaires. As Apple’s biggest shareholder, 25-year-old Steve Jobs ends the day with a net worth of $217 million. However, the big payday triggers internal tensions as it highlights Cupertino’s class divide.

August 19, 2004: Google floats its initial public offering on the stock market. Founders Larry Page and Sergey Brin turn into instant billionaires as the Google IPO cements the company’s status as a tech giant.

Relations between Google and Apple are good at the time, with Steve Jobs serving as a mentor to the company’s two young founders, and Google’s Eric Schmidt soon to join Apple’s board of directors. However, the peace won’t last long.

At $1.3 trillion these days, Apple’s a pretty darn valuable company. But how much could you have netted had you been smart enough to invest in the company in December 1980 when the stock first went public?

Obviously that depends on how much you’d have invested in the Cupertino computer company, and how long you had the nerve to keep the stock. A new report by CashNetUSA ran the numbers for a $1,000 investment in 1980. And, well, you’d be pretty happy with the results.

Sonos shares made moderate gains today during the company’s first day of trading on the Nasdaq. Investors don’t seem too worried that the smart speaker maker faces tough competition from the likes of Apple and Google.
