Reddit is a privately owned worldwide social news and media aggregation that got started up 13 years ago on 23rd June 2005.
Under this site, a variety of topics like news, movies, video games, books, fitness, music, science, food and more are covered with registered members submitting out contents in the form of links, images, posts which are then voted out by others.
These rated posts get the place among top Subreddit’s and if got highly approved then seek the front page of the site.
How it got started?
The origin of the site was made by Steve Huffman and Alexis Ohanian, the two roommates while studying at University of Virginia in 2005. The team managed to merge with Aaron Swartz’s company Infogami plus got acquired by Conde Nast Publications in 2006.
The major breakthrough came after receiving the place among the Hottest San Francisco Company list in 2010. In 2011, the site finally managed to operate independently of Conde Nast.

How to get to the site?
The entry to make a registration with the site is free of cost as it doesn’t even allow any email address. It is just adding the post upon the site as a user further getting the votes and comments on the topic and seeking out the visibility on the page.
The site offers points in the form of “post karma”, “Reddit gold” and “comment karma” for their high-quality content. T
he Reddit gold adds up the features offered from the site like highlighting, exclusive subreddit, ad-blocking, and personalized Snoo. They have also offered the purchase of Reddit gold for a price of $3.99/month or $29.99/year.
What they really do?
We can say Reddit as an essential resource or a message board just like bulletin board system which works as a self-correcting marketplace of ideas that is nearly impervious to marketers.
It has a little different from another social site Twitter as here the content is curated by the community itself. Under this, the useful contents or links are upvoted whereas the deemed unworthy ones are downvoted hence deciding out its position on the page and making it visible for thousands of people to see by sending boatloads of traffic to the linked website.
They even opt for Multireddits as a customizable grouping of subreddits through which users can navigate the communities of their choosing without being weighed down by the overbearing front page.
What makes it popular?
The real popularity came from the way of their dealing with the type of content that is valued, the discussion around it and the diligence with which users vet and expand on important topics.
They simply make you think, laugh out loud and motivate you to dig a little deeper. It is extremely self-referential and the comments are key as the most valuable discussion always bubbles to the top.
