Investigative reporting won new attention in the wake of the Watergate exposures of the 1970s, but few focused on the role of teamwork. Given the historiographical tendency to declare the Muckraking Era of the early 1900s the dawn of investigative reporting, this limitation of the popular reaction to Watergate was not surprising. In the twentieth century, the concept of team journalism is more often associated with "Time" magazine's institutionalized system of stringers, section editors, researchers, senior editors, and so on, than with such dynamic duos as Drew Pearson and Jack Anderson or Woodstein (Bob Woodward and Carl Bernstein). Early episodes in team reporting shared a key variable which sets them apart from the common run of "tour-guide reporting" where teams or individual reporters thoroughly describe the smells, sights, and sounds of the various locations under investigation. In each of the three cases examined--"Crowding the Poor/Appalling Pictures of Tenement-House Life"; the "Hell Hole" investigations; and the expose of the swill milk trade in New York--editors wanted a detailed investigation of several locations in a short time so that the separate scenes might be combined in a single article. In literary style and reporting technique, the team reports relied heavily on the elements characteristic of other tour-guide reporting. Using more reporters provided a more concentrated look at more scenes at the same time. The results in these cases were colorful, provocative stories of unusual sensory impact.
