Boston bombings

A graphic illustration of the highs and lows in a week’s worth of breaking (broken?) news coverage of the Boston Marathon attack.

ABC, CBS and NBC all announce additional coverage on Friday night to include the latest developments in the ongoing fallout from the marathon bombings.

In the frantic race to first with the news, the rival cable networks yesterday incorrectly reported that a suspect in the Boston Marathon bombing had been arrested, and they were not alone in gettng ahead of the story. AP and The Boston Globe also erred in saying that a suspect was in custody. ABC, CBS and NBC all broke into their regular programming to report progress in the investigation, but stopped short of saying there was an arrest or someone was in custody.

The bomb that exploded at the finish line of Monday’s Boston Marathon sent shock waves across the country.  Crime scene photos obtained exclusively by WAGA Atlanta are the first look at what is left of the deadly device.

Boston’s TV stations were on the story full time soon after of the detonations of two devices during yesterday’s Boston Marathon. They went wall-to-wall with within minutes of the explosions and, after overnight breaks, started up again early this morning. Drawing on video from the affiliates and others, notably Boston.com, the networks quickly got on board covering their explosions for the rest of the country and contributing supplemental reports, including President Obama’s appearance Monday afternoon.

Two explosions shattered the finish of the Boston Marathon on Monday, sending authorities out on the course to carry away the injured while stragglers in the 26.2-mile race were rerouted away from the smoking site. Here’s live video from WBZ and coverage from the Associated Press.
