PhocusWire first produced this visualization of digital travel company quarterly revenues going back decades in November 2019.
Since then the global financial markets have taken a huge hit from the COVID-19 pandemic.
The first signs of how much impact the crisis has hit the revenues of publicly traded companies became apparent when they released their first quarter earnings reports.
The chart has now been updated with the most recent figures, covering the first three months of 2020.
It is worth noting that some companies have yet to report their Q1 earnings (Hostelworld and Travelzoo), so they have temporarily fallen off the tool until their numbers are released.
The chart begins in 1995.
Several companies in international markets only report earnings on a half-year basis, which means their revenue numbers on the chart only change twice a year.
Foreign currencies were converted into U.S dollars, using the exchange rate at the time.
