With mining closed, the main business in Goa is tourism and it appears that the tourist resorts are some of the few businesses having enough money to advertise on local television channels regularly

There are many resorts advertising on local television channels like
Samruddhi Sanskruti resort
Sanskruti retreat, Pernem
Gaonkars Nandanvan
Nagesh Resort

During the monsoon the number of tourists in goa decreases, so these channels may be trying to attract local customers
