Historical text analysis and research

The 1966 championships was the very first to be broadcast to certain parts of the world via satellite, South American viewers were able to watch selected matches as they happened alongside those on the other side of the Atlantic watching live via Eurovision. In Britain, the BBC and ITV's coverage of the tournament was more comprehensive than ever before, a full camera crew covered every match and the two channels shared the same pictures, although not all were shown live as many games kicked-off simultaneously including the Quarter-finals. Frustratingly, the tournament was held just one year before colour television was launched in Britain on BBC2, but the final was at least broadcast on the higher definition 625-line channel as well as being shown on the 405-line services on BBC1 and ITV.
ITV had commentators at every match but had fewer live games than the BBC. 
A Eurovision title sequence incorporated both the names of the BBC and ITV, but this was probably not seen in British homes. For certain ITV had their own title sequence accompanied by a theme tune entitled "On The Ball" performed by The John Schroeder 
ITV games are in white, BBC or non-televised matches are in grey.
All matches were broadcast in black & white
England's victory over West Germany in the final was watched by 38 million people in the UK, with over ten times that number tuning in worldwide Live global coverage was not the only aspect of television coverage pioneered in 1966. Slow-motion replays were introduced to help the audience assess controversial incidents (although they weren't much help for Geoff Hurst's hotly disputed goal in the final) and the BBC employed a rotating panel of 16 pundits to provide expert analysis.

Similarities 

• Football was a worldwide phenomenon then and still is to this day
• Football and broadcasting was developing and always changing then and still is now

Differences 

• Black and white was what was being watched then now we have 3D TV's
• Social media wasn't invented then and now is ever important to our daily lives

The genre has changed as in it has developed drastically and you could say after every world cup something has developed. From then with black and white to colour broadcasting to now with social media playing an important role in how we watch the world cup.
