The PayPal Mafia is sometimes credited with inspiring the re-emergence of consumer-focused Internet companies after the dot-com bust of 2001.[7] The PayPal Mafia phenomenon has been compared to the founding of Intel in the late 1960s by engineers who had earlier founded Fairchild Semiconductor after leaving Shockley Semiconductor.[2] They are discussed in journalist Sarah Lacy's book Once You're Lucky, Twice You're Good.
