GIVE ANSWERS - English

I am reading a report of Ofcom about the development of media services in 2014. 

I came into these sentence :"The report
compares the availability, take-up and use of services in the UK and 17 comparator
countries." 

Now " take up" is likely to be a name and not a verb in this sentence, but I can't figure out what it is in this context.

May someone give me a simple synonim ?

thank you.
