It is common when you have more than one product.

Twitter has more than one product.

Off the top of my head:

Twitter App- Web, IOS, Android, Other

Twitter API

Twitter Firehose

Twitter Advertising

Twitter Analytics

Don't forget Periscope...not sure how that fits into the company structure though, admittedly

Isn't periscope being shut down?

That's vine I guess.

I think that's Vine.
