Priceline’s purchase of Kayak at a $1.8 billion valuation is yet another example of a well-established industry giant buying a nimble tech upstart to boost its portfolio.

Because Kayak’s key feature was price comparison, we’ve created a handy chart to compare the size and popularity of the two travel tech companies. While Kayak is dwarfed in terms of pure revenue (it went public just this summer; Priceline’s IPO was in 1999), its innovation and creative marketing made it a darling in the online travel world.
