When I was in Houston, I talked to a guy that managed several TV stations. I'm thinking they were LPTVs and I don't think they were carried by local cable systems. At least two of the stations were leased to two clients. One to an attorney that did two thirty minute infomercials each month and repeated hourly 24/7. The other leased to a car dealer that did two 60 minute programs a month repeating each one 12 times a day. Maybe they had some 'public affairs' or educational programming in off times, but I don't know. He had, if I recall correctly, 5 stations leased. I think 3 were to ministries that bought all the airtime.
