Most Americans associate summer’s three-day bank holidays with barbecues, trips to the beach and  family vacations.

I think of corpses.

Not that I am morbid or have a desire to work as an undertaker.  I simply had a recurring assignment early in my journalistic career to keep track of fatal car accidents on New York state highways each Memorial Day, Independence Day and Labor Day weekend.  And I had fun doing it.

Working out of United Press International bureaus in Rochester and Buffalo in the 1980s, I was the only staffer on duty  between New York City and Cleveland Sunday mornings.  My task was to scan newspapers and check in with UPI’s stringer network — friendly news people at local TV and radio stations  across the Empire State — for the day’s top stories.   UPI paid $40 per story, though the company’s numerous bankrupcty filings made the promise of receiving a non-rubber stringer check a running joke.

On the long  holiday weekends, UPI’s state and national wires  kept a tally of the number of people killed in auto wrecks.  We called this the CAX count, an acronym that meant something like car accidents or casualties.   The National Safety Council, an advocate for seatbelt use, would make a prediction about how many unfortunate drivers, passengers and pedestrians would expire between midnight Friday and the end of travel period on Monday.

Vincent Toffany, who headed the safety council, understood that the news cycle was typically very slow on these weekends.  His organization received branding and reinforcement of their messaging.  The American Automobile Association used this release-news-when-it’s dead approach, too, as did gasoline price survey author Trilby Lundberg.

What used to infuriate UPI’s archrival, The Associated Press, is when our prowess on the telephones with state police or stringers would yield an extra victim or two.  In some cases, UPI would be a tad liberal by counting a drunk who died by falling off a highway overpass or the victim of a pre-holiday crash who succumbed after the clock struck midnight.  AP usually relied on “electronic carbon” stories from its member newspapers, which meant AP broadcast subscribers in New York got late, stale news.

In any event, the UPI totals got a helluva lot more airtime and print coverage because I had a higher CAX count every time.

With UPI a shell of its old self — it’s now owned by Sun Myung Moon’s Unification Church and its News World Corporation, publisher of the Washington Times — and Reuters and Bloomberg doing a nice job with international and business news, there’s little traditional wire service competition for AP in the United States.  But demand for content among local print and broadcast outlets is down, too, as they lose audience and advertisers to an increasingly fragmented online media landscape.

The Associated Press still makes a significant amount of money off its 50 state reports, thanks to correspondents covering legislative news in statehouse bureaus and a policy not to display the content online, where it could be pirated.  But a reduction in the size of AP’s editorial staff and similar news cutbacks among media outlets that used to feed items to AP, has left huge holes in coverage.

What’s filling the gap? Regional newspapers are banding together to form cooperatives that may make even AP state reports unnecessary in the years ahead.  The Ohio News Organization is one such effort.   Politico also represents a significant threat, as it readily barters editorial coverage of Washington news for advertising inventory in local media outlets and web sites.

There are also some dark horses in coverage of the nuts-and-bolts local news.  Atlanta-based CNN has its own editorial staff plus a large network of domestic radio and television affiliates that both broadcast content from and contribute news to CNN.  The so-called CNN Wire has not yet become a comprehensive state-level news service, but it could.

Not surprisingly, newcomers without legacy business hindrances seem to be doing a fine job breaking news locally and globally.   The micro-local Watertown, NY, site Newzjunky is kicking the digital ass of the century-old Watertown Daily Times and making money by selling advertising.

Twitter is the no-cost platform through which the Dutch news service Breaking News Online reaches the majority of its 1.1 million followers, though it is also emailing and using RSS.  In a short time, BNO has gone from solely aggregating third-party news content in under 140 characters to a growing amount of original reporting.  While there’s no apparent revenue model, it wouldn’t surprise me to see local, state, national and vertical beats pop up under the BNO brand as consumers get hooked on digesting tweets and SMS headlines.

The word “wire” is less about a strand of copper these days.  I think of it as an acronym — World Instantly Reached Electronically — and relish the fact that so many content producers are joining in the fun.
