Which of the following is not an option within Custom Solutions?

Sponsored Influencer Program" is not an option within Twitch Custom Solutions. Custom Solutions typically involve bespoke, large-scale advertising initiatives designed by Twitch's internal creative teams to meet specific brand objectives. These often include "Twitch Tried and True" packages, which are proven, effective advertising formats, and "Experiential event activation," which involves creating immersive brand experiences on or off the platform. While influencer marketing is a core component of Twitch advertising, a "Sponsored Influencer Program" as a standalone, pre-defined Custom Solution option isn't how Twitch categorizes its bespoke offerings. Instead, influencer collaborations would likely be integrated into broader Custom Solutions or managed through other Twitch advertising channels.
