Step-by-step explanation:
The demise of picture magazines such as Life and Look can be traced mainly to the development of new media technology like television and the internet. With the rise of television in the mid-twentieth century, newspaper circulation began to decline, and the trend continued as more people turned to internet news sites and other forms of new media. The invention and widespread use of television, along with changes in print advertising, placed new emphasis on graphic images and recognizable brand logos, which became important in the visually saturated world we live in today.
