Google is still making efforts to establish itself in the social media sphere despite lagging far behind market leader Facebook.

The search engine giant recently acquired Polar, a startup that polls users to get their opinions on pop culture and other topics.

Polar was founded about two years ago and it boasts of 1.1 million unique voters in September and has served more than 500 million polls in the last eight months. According to Polar, the startup's polls have received votes from one in every 449 Internet users.

The polling questions allowed users to share their answers on Facebook and Twitter, include an MTV poll with the title "Which Melanie Iglesias Photo Do You Like Better" and an HBO poll with the title "Who is the most underestimated Game of Thrones character".

Polar will continue to offer its publisher tools until the end of the year after which it will shut down support for the other companies and mobile apps that use its polling services.

The Wall Street Journal reported that while Google is still working with its Google+ network, the site of social circles still isn't getting the attention it has in the past. Some top employees, including three designers, have left the social network recently.

Google+ has around 300 million monthly active users, where as Facebook has 1.2 billion users.
