Googlehad and incredibly great 2015. So much so, they introduced Alphabet - it's new parent company. Trading equity above $500 Billion USD, just 10% shy of Apple's value. If Google keeps at this pace, it will surpass Apple as being the world most valuable company. This mainly due to advertising revenue, while Apple capitalizes on the smartphone industry.
Alphabet's revenue mainly comes from Apple, which is ironic and informative at the same damn time. $1 Billion USD keeps its search bars available on iPhones in 2014 alone.
