Clearly worked enough with Onn brand for them to keep consolidating.
Just at the surface level this hurts:
1. Other brands selling TVs in Walmart.
2. Advertisement space will be cheaper for Walmart when they advertise on their own TVs, toeing the line of anti-trust.
3. Companies that offer advertising and data aggregation across TV brands will now have fewer brands to sell on.
4. Fewer consumer TV brands in general.
5. Walmart can adopt a loss lead model, they don't need to actually make money on the TV, they can make it up in 2-3 other places. Similar to AWS and Amazon.
