Google gives up on trying to make Google+ a real competitor to Facebook, Twitter and other leading social networks.

Google launched its social network Google+ four years ago, ambitiously trying to create a big social network with a billion or more people updating their statuses, posting photos and keeping in touch with friends.

On Monday, Google announced that users no longer need a Google+ account to engage with others on Google products. Rather, a Google e-mail account is now required.

In 2013, Google+ reported having over 300 million monthly active users, though the activity level of these users was questioned. Facebook had over one billion monthly active users at the time, now exceeding 1.4 billion.

A Google account will soon be all users need to share content, communicate with contacts, create a YouTube channel and more, across all Google products.
