I watched this TedX Talk from Tomi Ahonen and I think he may be right in his 'mass media' perspective.
1st mass media: Print (500 years old) including books, pamphlets, newspapers, magazines, billboards etc
2nd mass media: Recordings (from 1890s) such as music records, videogames, videotapes and DVDs etc
3rd mass media: Cinema (from 1910s)
4th mass media: Radio (from 1920s)
5th mass media: Television (from 1950s)
6th mass media: Internet (from 1991)
7th mass media: Mobile (from 1998)
8th mass media: ?
He makes the argument that augmented reality will be the next mass media and I think he is right.
