The average adult spends around 3-4 hours per day watching television, which adds up to approximately 21-28 hours per week. However, it is important to note that this can vary depending on individual preferences and habits. Some adults may watch more or less television than the average, depending on factors such as work schedules, personal interests, and lifestyle choices. Additionally, with the rise of streaming services and online content, the way people consume television has evolved, and individuals may spend time watching shows and movies through digital platforms rather than traditional TV channels.
