Notes: Local digital media (online and mobile) ad spending will grow by 13.1% to $35 billion next year, forecasts BIA/Kelsey. Overall local media ad spend growth is expected to be a more muted 1.6%, as traditional media ad budgets decline by 1.7%. By next year, then, digital will comprise slightly more than one-quarter of local media ad revenues, up from 22.6% this year. Local search ($7.2B) will continue to be the largest component of local digital media ad revenues, but will experience the slowest growth. Local mobile ad spend, however, is expected to shoot up by 54.2% year-over-year to $6.6 billion, outpacing display ($4.9B), social ($3.6B) and video ($3B).
