I know that parts of New Hampshire and Vermont are in the Boston TV market, and it's been that way for as long as I can remember. But with the population of cities like Manchester over 100, 000 and Nashua not to far from that, why hasn't a new TV market are been created for Southern and Central New Hampshire and adjacent areas of Vermont? I think New Hampshire is in a seperate TV market from Boston. As far as the area there not having their own CBS and NBC stations, I would think that with the changeover to digital that CBS and NBC could be on the digital subchannels of ch. 9 or 50.
That won't happen. One major factor is that CBS and Fox own the stations in Boston. It's not small broadcaster(s) community running the stations.
Even if Fox and CBS were to see the incremental revenue of starting NH stations, the resulting problem would be that that area can no longer be also part of Boston DMA. WMUR is just a one station grandfathered scenario, and Hearst profits on that exclusive niche.
Cable companies would refuse carrying the additional duplicative channels - it'd also cuts into their local advertising income revenue.
Also, Nielsen's DMA system is that counties are exclusive to one DMA.Nielsen would revise the DMA maps as a split of that from the Boston market - as The Viking mentioned above, meaning the original Boston stations lose market standing nationally. Thus, a negative sum gain.
Likewise, if Baltimore were to merge with Washington, not only does the city of Baltimore lose, but Hearst, CBS, Sinclair, EW Scripps would also. The four would prevent such from every getting idea. These are big broadcasters. CBS a network itself. Neither would want Baltimore to lose network statuses for the stations to become Spanish and religious stations for the entire DC metropolitan area.
In the end, even though population and demographics may have shifted (e.g. San Jose), and VHF and UHF allocations from the past may no longer mean as much as they do now, historic precedence wins.
