Just to satisfy my own curiosity, I did a little research to gain some perspective on the possible impact of Sinclair's "unprecedented programming decision". The
Sinclair Broadcast Group owns and operates 48 TV stations while having "Marketing Agreements", which entail little or no effective operational control, with 14 additional stations. There are over 1200 licensed telivision stations in The Continental US. 20 of the Sinclair Group stations are FOX affiliates (FOX Entertainment, not FOX News), 19 WB affiliates, 6 UPN affiliates, and 2 are Independents. Of the remaining 15, 8 are ABC affiliates, 4 are NBC affiliates, and 3 are CBS affiliates. While stations within the Sinclair Group theoretically may "reach" nearly 1/4 of all US households, that in no way means anywhere near that number of households watch Sinclair programming.
First, Sinclair stations are located predominantly in secondary or even tertiary "DMA"s, or
Designated Market Areas, according to
Nielsen Media Research.
Second, average nightly viewer share for any one of the "Big 3", ABC, NBC, and CBS, and often for PBS, is greater than for FOX Entertainment, WB, and UPN combined.
Third, only 6 of Sinclair's stations operate in the VHF band (channels 2 through 13), which itself far outdraws the UHF (channels 14 through 69) band.
Fourth, the bulk of the regular programming aired over Sinclair stations consists of second-tier-network series, minor-audience syndicated shows, reruns, re-released movies, local interest, and infomercials.
Fifth, in not one of the markets served by its stations is the Sinclair outlet the dominant station in that particular market for any timeslot ... often by a huge margin. In most of its markets, Sinclair's highest viewership occurs only during coverage of major sporting events, such as college or professional baseball, basketball, or footbal games, and NASCAR Cup races, when carried by FOX Entertainment. Typically, the lead-in and follow-on audiences are significantly lower than for the sporting event.
In short, it appears Sinclair's prime-time audience skews heavilly toward younger viewers, with a from-time-to-time smattering of other folks who don't happen to like whatever the "Big 3" plus PBS happen to be offering at the moment ... essentially what the trade terms "peripheral", as opposed to "key" (or "core"), audiences. I figure The Media is gonna pay far more attention to this "unprecedented programming decision" than will the viewing public. Discounting of what it may or may not be a harbinger regarding future broadcast general practice, this time around, its by itself very unlikely to have much effect on The Electorate.
