Like all the other news outlets on here, the Daily Telegraph will cover a variety of stories, ranging from the ridicioules story like this about a CEO rising a price to an absurd amount, to serious stories about death and news that have some sort of impact in the world
The flip side of the other story are stories like this, about real people who mattered and who have passed away and who were somewhat important in the world
The Guardian also covers important and serious stories, but are more professional on the issue, for example they won't use hashtags or pictures on a story about deceased people
They can also cover more silly stories like the one about the pope, as can be seen there are hashtags, emojis, images and a link to more explanation about the story as twitter has a limit of 150 characters, which limits what people can say on twitter
The New York Times is one of the bigger newspapers in America, not only centred about the city of New York or the state of New York, clearly as can be seen here now they cover stories from most of America, like in this tweet about Los Angeles and the city's plans of dealing with homeless people
They would normally cover stories about American celebrities or other international ones if they happen to do something bad or funny in the US. This tweet clearly being a bit more serious as it is about a dead person.
The Sun covers less serious news, centred about celebrities, gossip and speculation. The audience of the Sun will be younger people interested in gossip or older people who will find stories like this one interesting, because of course it is about quite an old topic like the original James Bond
Some of the Sun's stories are a bit more serious and have some sort of impact in the world but mostly they aren't, this is as serious at the Sun could get, as they would receive a lot of criticism for covering more serious stories like the refugee crisis because of the Sun's political bias, the conservatives being their preferred political party.
The Times of London covers the stories that people living in London might be interested in or might worry about, for example the refugee crisis, people in London are currently worried about the influx of refugees in London
Another side to the Times of London is this less serious tweet, about the Pope and his visit to America, in this tweet a hashtag can be seen and what seems to be a pope emoji with an American flag in the background
Vice normally covers somewhat goofy stories that involved either some random people who shared their experiences online, or if a member of staff or one of the producers does something crazy, for example one time a vice producer spent an entire week smoking marihuana and then talked about his experiences, or sent a film crew on acid to a monster truck show
They cover stories that involve real people and normally don't centre about celebrities and gossip, if any celebrity is on a vice article, it will most likely be a indie artists who is starting and happens to get a vice interview.
Most of these tweets contain hashtags when its an unimportant story like the pope in America, and the news outlets mostly don't use them in stories covering dead people in order to respect the ones who died. Most of them have an appropriate image if one is available. Virtually all of them have links because twitter doesn't allow for a whole news story in one tweet with its 150 character limit, and some of them tag other twitter users in them if a particular story is about them or if they are asking for a response or opinion.
They are using social media to promote themselves by having multiple twitter accounts that cover different news, like sport, economics, politics etc, and then the main twitter account would normally retweet the posts from the other outlets to promote them
