Television was created after WW1 in the late 20's
However, like the ASA, Ofcom is an organisation founded in 2003 that helps regulates what's viewed on television. This includes the 'watershed' where, between 5:30 am and 9:00 pm, channels cannot view shows distressing to children or with adult themes.
So far, Ofcom regulates BBC, ITV, Channel 3, Channel 4 and Channel 5. They also regulate radio channels, telecoms, mobiles, postal services and airwaves for wireless devices. In addition, they can also regulate Amazon Prime shows but not other applications like Netflix (as it is not UK based).
Print V Broadcast
Writing for print is a lot more casual than broadcast. With broadcast, you have about 30 seconds to introduce/talk about a news story, whereas in print you have a whole article to describe the situation. so you have the time to include opinions. For instance, there have been many cases where writers have had to apologise to certain people (celebrities, fans, etc) for any offensive points made in their articles. Similarly, articles can be more relaxed and use more jokes or puns, etc. For instance, Cosmo articles are very relaxed though can be about news.
However, the biggest difference is the detail involved. Print can describe the story in depth, using longer words and sounding very professional. However, in broadcast, you, again, only have limited time so you need to use simple words and have less detail. This is so people watching can understand fully what is happening in the story in the limited time.
Radio
Radio and podcasts helps to communicate through just audio, so it's good for when you're out and about rather than somewhere comfortable enough for television. There are a range of channels on the radio: mostly music; talkshows and shows like Radio One, which feature a range of types of channels in their show. Majority of channels feature the news.
It's different to TV for obvious reasons (lack of visual entertainment), but it's also a lot more descriptive as people have to describe or make it obvious with what's going on around them in radio. In television you can just see what is going on. Radio is usually a lot more informative and can also have a lot more humour involved.
