Nielsen announced the results of a second annual media consumption survey that found television and Internet usage continues to increase -- even though broadcast ratings have declined.
The measurement company said the average person in the United States watched 142 hours of TV a month, up 4%, from last year.
People who used the Internet were online 27 hours a month (up 6%) and those who watched video on mobile phones watched three hours a month (unchanged).
"Americans keep finding more time to spend with the three screens," said Susan Whiting, vice chairperson for The Nielsen Company. "TV use is at an all-time high, yet people are also using the Internet more often - 31% of which is happening simultaneously."
