The CEA association says that the U.S. has reached a critical junction in the adoption of digital TVs. According to them, digital TVs are now in 50% of American homes.

"I am proud to announce our nation has hit this digital milestone. With 50 percent of U.S. homes able to experience the reality of digital television, we have crossed a critical threshold," said Gary Shapiro, president and CEO of CEA. "2008 will continue to demonstrate the growth and success of DTV, with nearly 32 million units forecasted to ship. Consumers are particularly keen to add HDTV to their homes, with high definition expected to account for 79 percent of total DTV shipments in the U.S. in 2008."

The CEA says that DTV makers will post an 11% revenue growth to over $25 billion this year. By 2009 all broadcasts in the U.S. will be digital, freeing up the previously used frequencies for new data and wireless services.
