Daily Prophet's sudden change of heart

I wonder how did Fudge suddenly manage to get total control of Daily 
Prophet after Voldemort's return?
In PoA he seems more concerned that the story of Sirius's and 
Buckbeak's escapes may reach the DP and it'll have field day at his 
expense than with what a supposedly ravaging hyppogrif and a supposed 
extra-devious multi-murderer on the loose might do.
In GoF the DP seems eager to publish any sensational, unconfirmed 
rumor that can cast doubt at the MoM's effectiveness (e.g. dead 
bodies removed from the forest after the Quidditch Cup).
But right after Voldemort's return the DP suddenly becomes a MoM 
echo, which writes only what Fudge approves of (as Hermione and Rita 
Skeeter agree (OOTP, ch. 25, p. 567)), and not even Dumbledore's 
speech at the International Wizengamot about Voldemort's return (even 
more sensational than the death mark and bodies in the forest and 
certainly coming from a more reliable source) nor the defection of 
dementors from Azkaban (a similarly sensational and quite confirmed 
fact) causes the DP to print a single word of criticism.
I wonder how Fudge has suddenly managed to get such a total control 
over it, and, if it were quite easy to do, why hadn't he done it 
before? 

Nellie.
