Google planning to change 'iconic' homepage : Report

on 12:10 PM








Internet search giant Google is planning to change its iconic home page.

According to Google news website, Google System, the tech giant is said to be working on bringing its personalised homepage feature of its Android phones to the web and to its search page.

Google Now will take all your data and use it to create a completely personalised homepage customised to your needs and routine, News.com.au reports.

It would alert you to heavy traffic conditions and arrange an alternate route to work or tell you the live score of your favourite sports team, the report said.

The report pointed out that bringing Google Now to the web is designed to encourage people to move away from their current homepages which are often linked to their email addresses (Yahoo, NineMSN).
