According to a Nielsen's Three Screen Report which came out last year, the average American watches more than 151 hours of tv a month. The amount of tv time also increases with age. While teenagers spend only 103 hours a month watching tv, senior citizens spend 207 hours. That probably explains why you will find two or three televisions in an average American household. I have also noticed their penchant for buying tv's. When I go shopping, I always see an array of tv sets of different sizes, models and brands being displayed. People usually flock to the newest make and model to try out the features. Based on tv reviews, the lcd tv remains one of the most popular tv.
