Quote from Steve Louden – CFO @ Roku:
“We anticipate that our ad business will continue to grow substantially on a year-over-year basis, albeit at a slower pace and lower gross profit than we originally expected for the year.  We believe the behavioral changes by TV ad buyers are likely positive for us in the longer term — and that with more time spent at home, and many households curtailing spending in light of economic hardships, cord-cutting and the shift to streaming will continue to accelerate.”
