Forget about prime time, Americans are watching their favorite TV shows online when and how they want, according to the "Digital Life America" survey of 1,150 Americans ages 12+ conducted by Solutions Research Group.

More than 80 million American Internet users have watched a television show online, representing 43% of the total online population. This is a sharp increase from just one year ago, when only 25% were watching online.

In addition, 20% of Internet users polled are watching shows online on a weekly basis.

Time shifting strongly correlated with age. Overall, 25% of respondents had time-shifted a prime time show using either a DVR, broadband, mobile or some other device. Among 18-to-34-year-olds, that percentage rose to 34%.

As these trends continue and more content becomes available online, television scheduling may be a thing of the past. [eMarketer]
