Ad tech shop Sled Mobile launches a platform that prices ads by time

Cost-per-impression ad pricing is so yesterday. A New York City-based ad tech shop is today launching a limited beta of what it describes as the first-ever cost-per-second (CPS) platform for ads.
Sled Mobile’s Parsec platform is based on the idea that the key thing display advertisers want is user attention. Time spent with the ad, CEO and founder Marc Guldimann told me, is “a proxy for attention.”

Currently, the platform only supports mobile web, although Guldimann told me it will be able to handle in-app ads within a few months.
