Which scenario is an example of social media influencing mainstream media content?
for apex answer is a factory worker uses a popular photo-sharing app to document unsafe working conditions, which leads to an investigative report by a local news station.

a fast-food worker uses twitter to organize a protest for workers who want higher wages, leading to widespread coverage of the issue in the news apex

explanation:

the social media has been occupying a space previously oligopolized by the mainstream media, influencing even the electoral campaigns.

a very clear example of the effect of social media on mainstream media is after the president donald trump's tweets. he chose a social media platform to communicate with the world and every tweet he writes turns to traditional newspaper stories in the us and around the world.

in addition, you can say that even the traditional media vehicles have joined social media. all tv channels have accounts on twitter and instagram.

good question. i'll be looking into that. (this is a joke sir)
