First they say this:
So we went to our data folks on the MediaCensus side of MediaBiz. And we asked for the "REAL" HD counts. In our definition, that means a channel that (1) labels itself an "HD" network; (2) is available nationwide; (3) is NOT a pay-per-view or VOD service; and (4) is not a broadcaster.
Then they say this:
And yes ... we know that not all self-proclaimed HD networks are "true" HD 24/7. We also know that our 'national' criteria cuts out some very popular regional sports networks, a move which primarily disadvantages the extra-robust sports selection from DIRECTV.
Uhhh...No it doesn't. According to your "national" criteria, RSNs do fit within your counts.
1) Do they label themselves as HD? Yes
2) Are they available nationwide? Yes
3) They are not a PPV or VOD service? Yes
4) It is not a broadcaster? Yes
So, why should a full time HD RSN not be included in a count? I can actually pay to watch any full time RSN 24/7, including out of market pro games.
