I want to know the answer to the following question:
What impact was Mackenzie said to have?
All the background I'm provided with is that "The new editor of The Sun, Kelvin MacKenzie, took up his post in 1981 just after these developments, and "changed the British tabloid concept more profoundly than [Larry] Lamb did", according to Bruce Page, MacKenzie". Is that enough to answer the question?
Answer: yes
