The wizarding world seems to rely mainly on newspapers (the Daily Prophet) for their news. They have no T.V. although they do have radio.
The wizarding world treats Quidditch like Muggles treat football so I would expect a lot of interest in new/breaking Quiddith scores. As this is the case do wizards have some way of watching live Quidditch matches other than going to the event?
While they have no need of mundane domestic objects such as dishwashers or vacuum cleaners, some members of the magical community are amused by Muggle television, and a few firebrand wizards even went so far, in the early eighties, as to start a British Wizarding Broadcasting Corporation, in the hope that they would be able to have their own television channel. The project foundered at an early stage, as the Ministry of Magic refused to countenance the broadcasting of wizarding material on a Muggle device, which would (it was felt) almost guarantee serious breaches of the International Statute of Secrecy.

Wizards who are unable to attend must read about it in the papers. (Quidditch matches will often last longer than a day, so they can still almost "follow" the match as it goes.) By matches such as the 2014 Quidditch World Cup, the Daily Prophet will even print live coverage (whatever that's supposed to mean).
