In 1998, one of the first examples of distributing and selling media content through the mobile phone was the sale of ringtones by Radiolinja in Finland. Soon afterwards, other media content appeared, such as news, video games, jokes, horoscopes, TV content and advertising. Most early content for mobile phones tended to be copies of legacy media , such as banner advertisements or TV news highlight video clips. Recently, unique content for mobile phones has been emerging, from ringtones and ringback tones to mobisodes , video content that has been produced exclusively for mobile phones.
As the accompanying table shows, a majority of all age groups agree that it is generally acceptable to use a phone in three general public situations: when walking down the street, while on public transportation, and while waiting in line. Using a phone at a restaurant is the only situation in our survey for which half (50%) of young adults find it generally acceptable to use a cellphone, but for which a majority of older adults consider cellphone use to be generally not acceptable. The vast majority of Americans — including young adults — do not think it is acceptable to use phones at a family dinner, during a meeting, at a movie theatre, or at church or worship service.
