It is now very convenient to access and get the products and services that we needed in life because almost everything is already digitized. That is because of the power of the internet. Products that were just available through personally visiting a store are now accessible in the comfort of your home. It has been said that products are now "just one click away." Both physical and digital products are easy to get through online stores. The concept of "market" has also changed because of the internet. Before, it only refers to a place where personal selling and buying are done. But now,  the "marketplace" is anywhere. A school or a training institution is known as a place where students and learners go to. Now, you can study at home, attend online training while in front of your computer. Books can now be read on almost any device: computers, tablets, and phones.
