When something happens that causes a lot of things to change, you can say that the event "had a huge impact". For example, you could use this phrase to talk about changes in technology:
The advent of the Internet has had a huge impact on every aspect of society in the last 20 years.
This means that the Internet has changed almost everything in our society. Here's another example, talking about music:
The rise of hip-hop music in the 1980s has had a huge impact of popular culture.
Instead of "huge" you can also use words like:
an enormous impact
a gigantic impact
an undeniable impact
