Most communities -- mine is no exception -- has at least three "public
service" channels.

One is the Community Access station. Anyone who wants a show can be a TV
star. He/she must take a course and learn how to use the equipment
properly, and the show cannot be commercial in nature or have an 'aroma'
leading back to a commercial venture. In my town a lot of that broadcast
time goes unused.

There is also a government access channel. Events such as city council,
school committee, cable TV committee meetings, etc. are carried there, as
are a few governmental ceremonial functions.

There is also a school department channel. The high school has a studio.
There are, two problems with cable TV and high school sports --

1) There has to be a production team willing to do the work -- usually
within the school itself and students will not commit to it

2) Here in Massachusetts, those that control high school athletics are a
little antsy about live television of high school events. They harken back
to the 1950s, when the NFL wouldn't put sold out home games on TV, fearful
that attendance would eventually erode. Times have changed. Those that
run high school athletics have not.
