How have cryptocurrencies been covered on television news? The timeline below shows total mentions of "cryptocurrency" and Bitcoin, Ethereum and Dogecoin over the past decade, showing an initial glimmer of mentions from 2013-2015, but that coverage of cryptocurrencies did not really take off until December 2017 when Bitcoin reached a valuation of $20,000 per coin. Mentions again took off in January of this year and have increased steadily month over month as it has attracted ever greater prominence.
