Search is still the bread-and-butter business for GOOG at this point, despite its "other bets" - like Nest, Verily and Google Fiber, among others. However, some of these other bets are paying dividends. While Google has had a few swing-and-miss moments, others like Waymo have paid off big time. The unit has been valued at $70 billion by some analysts and as self-driving cars become more prevalent, you can bet Waymo will be playing a larger role.
