The art of television watching is about to change for people with analog television sets. Change as in cease.

There'll be a test on Thursday, when broadcasters interrupt programming on analog sets to remind people about the change.

Starting June 12, analog signals will no longer be broadcast, so only the new digital televisions, or analog televisions hooked up to a digital converter box, will work.

But not everyone knows what kind of television they have, so Thursday's test will make it clear. In the Twin Cities, broadcasts -- on analog only sets -- will be interrupted three times for five minutes, with a message about the June 12 transition. Basically, if you can see it, you've got a problem.

Test times are: 7:25 a.m. to 7:30 a.m., 12:25 p.m. to 12:30 p.m. and  6:25 p.m. to 6:30 p.m.

The Nielson ratings company reports that the Twin Cities area is the 15th worst prepared of the 56 metered markets. About 3.7 percent of households here aren't ready, compared to the national average of 2.9 percent.

Online help is available for those uncertain about what to do. People can also contact the Volunteers of America DTV hotline at 612-623-4063.
