Not long ago, Google announced that it would be restructuring the company using a new company called Alphabet to oversee the new, separate sub-companies. The premise was that each endeavor should have its own company under one parent company, so the failures of each endeavor won’t hurt Google as a whole. So Google is now focused on search and mobile, and different divisions are left to do what they do best.
The company announced that the restructuring will be completed by the end of the day today, October 2, and Google stocks will begin trading as Alphabet stocks on October 5. However, the previous ticker symbols of GOOG and GOOGL will remain.
