Many APIs eventually find their way to the ProgrammableWeb deadpool. They end up there for various reasons: no business model, replaced by a newer service or ceased being useful. The most popular of these dead APIs are predominantly from two big tech firms: Google and Yahoo. Search and mapping make up the bulk of the functionality behind these 12 popular--but no longer available--APIs.
Earlier this month I eulogized the Yahoo Maps API. It was launched the same week as the Google Maps API and for some time was often mentioned at the same time. The Yahoo Maps API, it appeared, was to be disconnected by now, but it appears the company is going to wait a bit longer.
