I knew it was hight, but not this high:
In 2001-02, reality TV accounted for about 22% of the prime time TV audience watching the top 10 programs. By 2010-11, it accounted for about 56%, an increase of almost 155%. And 2010-11 did not mark the height of reality TV’s popularity during the past decade. In 2007-08, reality TV comprised more than three-quarters (77%) of the audience for the top 10 prime time TV programs, meaning it is down 27% from its peak popularity.
