When broadcast TV transitioned
from analog to digital, the new technology provided each broadcast TV station
with significantly more capacity. With
digital broadcasting came the ability for TV stations with a single channel to
transmit more than one program at the same time. If you are an over-the-air TV viewer you know
that your favorite local TV stations have multicast channels. So if you are watching Channel 9 you also
have the option of watching 9.2 and 9.3. Most of the local stations have one or
more of these multicast channels. In
fact Channel 14, one of the local PBS stations, offers 5 distinct digital
programs on a channel that during the analog period could broadcast only one.
When first launched, local TV stations
looked forward to this expansion. In the
blink of the eye they went from having 24 hours of broadcast time per day to
48, 72 or more hours. And along with
these expanded hours would come increased advertising revenue. Over the last decade that this expanded
capacity has been available, it is interesting to note that stations are still
trying to figure out what to do with it as the advertising bonanza has not
materialized.
People are creatures of habit
and getting large numbers to find and sample the programming has been a
challenge. Good programming is expensive;
purchasing high priced shows for small audiences didn’t make sense.
Some stations tried offering
special services like Channel 9’s continuous local weather loop. With smartphones and tablets providing more
current information it was no wonder that the audience was miniscule and the
service has been cancelled.
So, that advertising bonanza
has turned into Bonanza or Daniel Boone or Perry Mason or any one of many programs
from TV days past. MeTV, a multicast
channel of WLWT Channel 5 carries round the clock reruns from the last century.
Recently, Channel 9 launched Laff TV and Escape TV. I watched a few of the shows on Laff and
didn’t do all that much laughing. The Escape Channel is not much better as
series such as Resurrection from the
1980s or Presumed Innocent from the
1990s, unlike some fine wine, have not gotten better with age.
