Flat to Down to Way Down:

Music: sales last year were down 21% from their peak in 1999
Television: network TV's audience share has fallen by a third since 1985
Radio: listenership is at a 27-year low
Newspapers: circulation peaked in 1987, and the decline is accelerating
Magazines: total circulation peaked in 2000 and is now back to 1994 levels (but a few premier titles are bucking the trend!)
Books: sales growth is lagging the economy as whole


Up:

Movies: 2004 was another record year, both for theaters and DVDs
Videogames: even in the last year of this generation of consoles, sales hit a new record
Web: online ads will grow 30% this year, breaking $10 billion (5.4% of all advertising)
