Both Expedia and Priceline are strengthening their positions as the most successful and, some argue, innovative companies, constantly gaining share in the category in the process.
Priceline managed to record the sharpest growth over the 2004-2013 period, which allowed the company to stand beside Expedia at the top of the global online travel agency and travel intermediary ranking in 2013.
Competition between the two OTA giants is getting tougher in 2014, with Priceline continuing its sharp rise and Expedia also achieving a remarkable performance.
