I know the direct usage of the word now when it pertains to something that is happening in a specific moment of the present (the very present you can say). But what about other situations?. I was writing this essay and I wrote this :
Whereas in the past books were the main source of knowledge, the arrival of the internet has drastically altered the relevance of books, because of the easiness in which such information can now be accessed.
And also this part:
For example, now it is possible to press a button and obtain information that is not only written but also visual and auditive.
Is the usage of the word "now" in the above sentences appropriate?
I think that in both cases "nowadays" can replace "now" and be accurate and correct, right?
Thanks in advance
