The promise of increased differentiation in local television news prod
uced by new technologies in a multichannel environment prompted this s
tudy. After comparing 1,335 stories from nine TV stations in Texas, th
e data showed that 56% of the reports on local newscasts were similar
(consonant) and 44% were different (unique). News stories from network
sources presented the highest percentage of similarity, while unique
stories were usually supplied by local sources.
