Now Twitter has done it all.
The San Francisco-based social network has helped spark revolutions across the globe, reunited a homeless man with his daughter and now a rail-riding dog has found his way back home thanks to the imaginative minds of Jack Dorsey, Evan Williams and Biz Stone.
A Jack Russell terrier hopped on board a train heading towards Dublin, Ireland without its owner.
Irish Rail employees found the dog and tweeted a photo of it out in the hopes of finding his owner.
The dog was turned over to a local train station for safe-keeping when operators confirmed that his owner was not on the train.
In just half an hour the image was retweeted more than 500 times before landing in the Twitter stream of the dog's owner Deirdre Anglin.
The woman who lives an hour train's ride away from Dublin in Kilcock, County Kildare tweeted the rail line saying it was her dog Patch.
Anglin credited Twitter's ability to make any piece of information go viral with helping find her dog.
She had also gone on Facebook to post photos of her missing dog, but it turned out Twitter was better at solving the case of the rail-riding Jack Russell terrier.
