ANCHORAGE, Alaska -

For the first time in more than three decades, commercials promoting Alaska tourism are airing on national broadcast networks, with one commercial that features winter-only tourism.

"This is the first time we've had a TV spot that's completely dedicated to winter promotion," said Kathy Dunn, the state's tourism marketing manager.

The six ads are airing during morning and evening news programs. The state spent $1.2 million for the commercials to air in an effort to attract more tourists to Alaska during the summer months and the off-season. The number of visitors travelling to Alaska during the winter months has slightly increased and the state is working with the tourism industry to discuss how to develop winter tourism and take it to the next step, according to Dunn.

"You want to make sure you have enough product, different activities and attractions that they can go and enjoy," said Dunn.

According to Julie Saupe, president and CEO of Visit Anchorage, the city can support more tourism during the off-season. Visit Anchorage markets Anchorage as a destination for business meetings and conventions during the colder months, in an effort to feed the local economy.

"We think we've got great product up here for winter tourism for the leisure traveler in addition to the convention traveler," said Saupe.

The commercials began airing September 30 and will run through November 5.
