A lot of time is occupied by smartphones. People do many things with smartphones. Through handheld phones people can purchase goods and conduct personal banking. The structure of the market was changed altering use from television and computers to smartphone.

With the Internet, we can easily access the world news and can search for things wondering easily. Through various sites, you can watch interesting videos or spend free time with game app.

Not all these innovations are good ones. With the growing number of online stores, many jobs are missing, such as the number of employees at market and bank, which has traditionally been on the payroll. Fewer people read books therefore printing industry are decreasing. Private Internet space is easily accessible, so there is a problem with protection of privacy. Communication between the family and friends are dwindled because of spending most time using smartphone. In the cafe, people can easily see who are looking at their cell phones.

Instead of taking pictures straight with your cellphone, try to entertain people’s face and views on your mind. Efforts are necessary not to search information on the Internet, but to seek answers. Sometimes you turn off cell phone and look at the light of nature, feel the sunlight. There are many interesting stories in the cell phone, but it is more important to have fun in the conversation with your family than to experience a deeper joy in conversation with your family and friends.
