I don't know about other countries but in Romania I know the story way too well: some commercial sport chanell will buy the rights, will brag endlessly about having the rights to the most prestigious event in tennis
( or something of the sort, one chanell used to advertise ATP Masters Serie like the Tennis CL
) and then switch the coverage of Montanes-Fog match at 6-6 in the 5th to some Steaua friendly off-season football match with some 4th League German team
I lie you not, it did happen countless of times.....
And personally prefer to watch tennis on TV, I settle with LS when there is no other way but I much prefer the TV
