Online advertising spending fell 5 per cent in the second quarter to $13.9bn from the same period a year earlier, research firm IDC said Wednesday, with the more developed US market declining even more, by 7 per cent.

It marked a second consecutive period of declines, and IDC said that there will likely be between two and four more quarters of the same.

Asia bucked the trend and showed an overall increase in online ad spending.
