In the nineties I took part in the search for extraterrestrial intelligence by providing my idle computational resources from my home PC to look for patterns in the noise coming from outer space. The amount of radio noise coming from outer space is overwhelming but SETI@home, University of California, Berkeley Space Sciences Laboratory and millions of participants tried to find the patterns that would suggest extraterrestrial intelligent activity.   This activity is quite similar to what is going on with big data in today's business world.
