  • What is Xfinity?

    Xfinity is the largest Internet service provider in the United States. It is a subsidiary brand of Comcast. Comcast founded in the mid-1960s and provided the cable television services initially to its customers, and the user base increased to tens of millions of customers in a few years all over the US. In the '90s, Comcast started offering Internet services to its users which resulted in increased market share to almost 40% of the whole US Internet market.

    Xfinity formed in 2010 by Comcast, and the reason for its formation was that the Comcast company was initially set up to offer the cable services and television, and wireless services. The marketing team felt uncomfortable with attaching each new facility to Comcast brand and striving to keep it narrow-focused on what it was meant to be. Therefore, Xfinity explicitly launched for providing Internet services, TV, and wireless services. Hence, the Comcast television was named Xfinity TV, Comcast High-Speed Internet was named Xfinity Internet. Today, people majorly knows Xfinity, and fewer people know that both the brands owned by the same Company.

    What is Internet Speed Test?

    The Internet speed test truly checks the actual Internet connection speed of your Internet. The Broadband speed is measured by checking download speed as well as the upload speed. A slow Internet means that web browsing is affected as well as the downloading of data is affected. The upload speed is always less than the download speed in most cases under most ISPs. It is because the download speed is needed by most of the consumers, especially the home consumers. Because home consumers use Internet majorly for browsing the web and downloading the files from the Internet. Upload speed is required by those consumers who want to upload a vast amount of data to the Internet.
