  Social media is currently one of the most important means of news
communication. Since people are consuming a large fraction of their daily news
through social media, most of the traditional news channels are using social
media to catch the attention of users. Each news channel has its own strategies
to attract more users. In this paper, we analyze how the news channels use
sentiment to garner users' attention in social media. We compare the sentiment
of social media news posts of television, radio and print media, to show the
differences in the ways these channels cover the news. We also analyze users'
reactions and opinion sentiment on news posts with different sentiments. We
perform our experiments on a dataset extracted from Facebook Pages of five
popular news channels. Our dataset contains 0.15 million news posts and 1.13
billion users reactions. The results of our experiments show that the sentiment
of user opinion has a strong correlation with the sentiment of the news post
and the type of information source. Our study also illustrates the differences
among the social media news channels of different types of news sources.
