Henry Blodget’s Silicon Alley Insider has some interesting data and analysis (Q2 2006 vs. 2007) that shows how Internet media are gaining at the expense of traditional media: TV, newspapers and radio in particular. Among traditional media, only outdoor grew in Q2. Everyone knows this intuitively and anecdotally but Blogdet breaks out some numbers.
In the aggregate he says traditional media shrank by 3 percent YoY vs. online, which grew 42 percent. The total advertising pie grew 8 percent vs. last year.
