Retirement Benefits [Abstract]
BENEFIT PLANS	BENEFIT PLANS HomeAdvisor HomeAdvisor employees in the United States are eligible to participate in a retirement savings plan sponsored by IAC, which is qualified under Section 401(k) of the Internal Revenue Code. Under the IAC/InterActiveCorp Retirement Savings Plan (the "IAC Plan"), participating employees may contribute up to 50% of their pre-tax earnings, but not more than statutory limits. The employer match under the IAC Plan is fifty cents for each dollar a participant contributes in the IAC Plan, with a maximum contribution of 3% of a participant's eligible earnings. Matching contributions under the IAC Plan for the years ended December 31, 2017, 2016 and 2015 were $3.5 million, $2.7 million and $1.9 million, respectively. Matching contributions are invested in the same manner as each participant’s voluntary contributions in the investment options provided under the IAC Plan. An investment option in the IAC Plan is IAC common stock, but neither participant nor matching contributions are required to be invested in IAC common stock. The increase in matching contributions in 2017 and 2016 was due primarily to an increase in participation in the Plan due to increased headcount as a result of business growth. Internationally, HomeAdvisor also has or participates in various benefit plans, primarily defined contribution plans. The Company's contributions for these plans for the years ended December 31, 2017, 2016 and 2015 were $0.3 million, $0.1 million, and $0.2 million, respectively. The increase in the Company's contributions in 2017 was due primarily to an increase in participation in the Plan due to increased headcount as a result of business growth and acquisitions. Angie's List Angie's List sponsors a 401(k) profit-sharing plan (the "Angie's List Plan") covering substantially all of its employees. Contributions to the Angie's List Plan are discretionary.
