Subchannel Report will not be published again until Monday August 18, 2014
Since adding the cable data into Subchannel Report we have made the editorial decision to now suppress hundreds of listings of subchannels that are essentially duplicates of other signals in the same markets. If we continue to report on these channel duplications we could inadvertently be reporting higher cable subscriber counts (and station counts) for networks and broadcast groups.
At this time we will not be making any changes to low power (no cable) channel listings unless the low power is either a satellite, or translator, for a larger station in the market. However, we also have a major change coming to LPTV stations without cable distribution outlined below.
Upcoming database changes:
Satellite stations – satellite stations that rebroadcast a TV station in the same market (without its own station IDs, commercials, or news) will be suppressed and not shown in any results. If the primary station is a low power, which is rebroadcast onto full power stations, cable carriage will be attributed to the primary station.
Semi-satellite stations – satellite stations that rebroadcast a TV station in the same
Market (with station IDs, commercials, and news) will be included in the listings for the time being. An editorial decision may be made in the future to also suppress those semi-satellite stations, which don’t have a news presence.
Duplicate signals – TV stations rebroadcasting a sister channel in the same market on a subchannel will find that rebroadcast subchannel now suppressed. In rare cases, whereas the duplicate signal is reaching into corners of a large market Subchannel Report will make an editorial decision whether or not to keep the listing active.
Low Power – no cable households – Beginning next week Subchannel Report will only be reporting the actual over the air households of a low power (without cable) rather than attributing the total TV market households to the station. In some cases the low power will be suppressed if it is a satellite of a larger TV station in the same market.
We will take care in the review to not suppress station segments that will skew up and coming networks. In addition, we maintain a suppression file of stations and channels at Across Platforms and we will be happy to receive feedback and correct any errors we may make. A review of thousands of listings is currently underway and we expect future adjustments after the break. We believe that this change will impact about eight to nine percent of the listings.
In the near future we will also begin the process to attribute MVPD Provider data to LPTV-Cable stations and subchannel networks.
Note: About 1,000 historical reports of Subchannel Report will automatically be updated once these new changes to our methodology take effect.
