Remember the "right to be forgotten"? It's been a year since the EU Court of Justice ruled that search engines must "delist" out-of-date or inaccurate links in results if requested, and the anniversary has been marked with a set of stats from Google—and a demand for more data from 80 academics.

The law was actually in place well before last May, but it was then that it was upheld in a court case brought by a Spanish man. From that point, the EU required Google's European sites—as well as rivals such as Bing—to remove links when requested if they meet a set of data protection criteria. Regulators left it for Google to decide which requests to approve or not, and it now has a team of lawyers analysing each one.

The controversy around the right to be forgotten hasn't calmed: the UK's data watchdog is questioning Google's decisions, academics are calling for more transparency over the process, and the EU is pushing to extend the delinking effort to Google's global sites.
