There are too many advertisements in everyday media. This is especially true in many free software like websites, apps and television ads where it ruins the experience for many people. Although, I don't believe that advertisements should be removed as a whole because many businesses rely on them to make money.
Although some people believe that advertising is annoying(myself included), websites need them for a source of income. The amount of free websites and games would be drastically reduced. TV and radio stations would have no source of income other than donations, which simply isn't enough for them to operate. If we reduce the number of advertisments, then the quality of the content they are giving us is reduced, since they have less funding.
