I can think of 2 main strategies:
(1) work inside the system: create newsworthy stories that the mainstream media will cover that get out the message - be really strategic about this (timing, framing the issues); do trainings for progressive activists and aides to candidates/elected officials on how to do this successfully
(2) develop alternative forms of media -- this includes content, networks, and distribution channels (examples: the new liberal radio network, progressive columnists, blogs). The theory is that these alternative forms will grow larger audiences, get broader distribution, and then influence the mainstream media.
(3) grassroots one-on-one media -- really take house parties, town hall meetings, flyering and tabling to a new level.
What am I missing?
Which efforts are already underway that seem to be the best thought out, most likely to succeed, etc.?
What are the major challenges?
I'm convinced this is really important, and I'd like to form an online team to think more about both the vision and the strategy. Are you interested in joining this effort?
