American local TV station online 24/7

I've discovered that a local TV station in Witchita, Kansas, broadcasts a channel online 24/7. KCTU's internet channel is different from the broadcast channel, but it does show one thing. If a small local TV station in Witchita can sort out broadcasting 24/7 on the web, why can't some other TV channels do the same?

This all came about as a result of the station losing their affiliation with ION Television, originally known as the PAX network. Kudos to KCTU for a fine idea, well executed.
