Google currently fields more than 100 billion searches per month. For the first time, mobile devices have surpassed PCs as the device of choice for performing Google searches worldwide. “The shift to mobile has prompted Google to rethink its core business, which places ads based on keywords typed into the company’s search engine,” explains The Wall Street Journal. “New types of devices, from phones to tablets to cars to wearables, will require new ways of searching.” Since many of these devices do not necessarily rely on typing text, Google is looking at technologies such as voice and image recognition moving forward.
