We have a lot of casinos in the industry and all of these casinos have their own specific places that they gets their updates from and to be truthful the medias too also influence the odds because the Media's are what broadcasts the news if any players will play the games or not and from there the casino will decide if they will increase their odds or reduce it.
I think it is necessary because now there is interdependence between the media and also the casino in making decisions after there is certain news from the media. Especially if in a team like football there are players who can make a big impact in the match so that the potential for the team to win can also be quite large so that the casino itself can take the right steps to make a difference in the bets that they will open to the public. So the media and the casino do need each other for their respective purposes.
