According to CTIA, the wireless industry trade group, U.S. mobile users consumed 1.1 trillion megabytes of data between July 2011 and June 2012.

It's no secret that Americans are using more and more data, thanks to smartphones and tablets, but the grand total might be a little surprising. According to CTIA, the wireless industry trade group, U.S. mobile users consumed 1.1 trillion megabytes of data between July 2011 and June 2012.

That's a lot of episodes of Gossip Girl on Netflix.

Last year, CTIA found that consumers ate up 568 billion megabytes of data, or a 104 percent increase year over year. Consumers aren't spending that much more time on their devices than they were last year - 2.321 trillion minutes vs. 2.251 million between 2010-2011 - so it appears they are just tapping into more data-intensive services streaming video.

Texting was also up about 3 percent from 2.206 trillion messages in 2010-2011 to 2.273 trillion between 2011-2012. Multimedia messages, however, were up 10.6 percent to 58.3 billion this year.

At this point, about 41 percent of the 322 million wireless subscriber connections in the country are smartphones, CTIA said. There are currently about 22 million tablets in the wild, or 17 percent of all wireless connections. There's also been about a 10 percent boost in the number of pre-paid wireless customers.

While the number of smartphones are up 37 percent over the last year, it was wireless-enabled laptops, tablets, and modems that saw the biggst jump at 42 percent to 21.6 million, CTIA said.

According to CTIA, meanwhile, the average monthly wireless bill also dropped in the last year, but the savings aren't exactly going to boost your savings account - prices went down $0.07 to $47.16.

CTIA used these stats to continue its push for more spectrum. The group's members - which includes the top carriers in the country - might soon be able to get their hands on some excess spectrum. The Federal Communications Commission last month formally , which will offer up broadcast spectrum for mobile broadband use.
