Ad network 3
• Early-mid 2000s:
• piggybacking becomes commonly used to fill remnant inventory,
• endless redirects cause some ads not to load at all,
• ad networks’ struggle with “liquidity” problem - their inventory is either under-filled (not enough campaigns) or over-filled (too many campaigns)
2005
Early “ad exchanges” launch
