In general, I'm pretty busy with the other things I charted ... I bought a piece of a sports-tech company. We do a lot of work with at the Clippers. I think that'll be great. We're really looking at the possibility of extending and building a real over-the-top distribution channel with value-added services for the Clippers, that could lead to other partnerships and investments.

I'm very, very bullish about our prospects, and as I tell our board, as I tell our employees, this is the time to invest. There's so much opportunity. Let's just invest in that opportunity, and really get after it.
