iGoogle is the name of a former service offered by Google that functioned as a web portal. The web portal could be customized to fit one's needs and be set to replace the end user's Google homepage. Users put gadgets on their homepage such as RSS readers, YouTube videos, Gmail inbox and many more. The default Gadgets were the Date and Time, CNN.com, Gmail, Weather, and the Official YouTube Gadget. iGoogle was customizable with themes, some of which changed over different time periods.
Google officially closed down the service on November 1st, 2013. The announcement was as follows:
"On November 1, 2013, iGoogle will be retired. We originally launched iGoogle in 2005 before anyone could fully imagine the ways that today's web and mobile apps would put personalized, real-time information at your fingertips. With modern apps that run on platforms like Chrome and Android, the need for iGoogle has eroded over time, so we’ll be winding it down. Users will have 16 months to adjust or export their data." - Matt Eichner
