Both multimedia options feature photos, local videos, and national videos.
The Washington Post's multimedia options are certainly greater than the Pioneer Press. The Press, as a local news organization, is more focused on local news. The Post is a national affiliate, and therefore has more news covering the national level.
Multimedia options do a great job of presenting a story through photographs or video instead of words.
The language in multimedia stories is different, it doesn't always have to be past-tense. The captions describe what is going on in the pictures, while still progressing the story forward by saying how that picture relates to what the story is about.
